Top 10 Security Testing Tools

Security testing tools identify vulnerabilities in applications and infrastructure before attackers can exploit them, spanning static analysis, dynamic testing, and penetration testing across the development and production lifecycle. The value of any testing tool comes down to detection accuracy and how well findings integrate into development workflows. We reviewed 10 platforms and found Aikido Security, SonarQube, and Astra Security Pentest to be the strongest options for most security programs.

Application security testing covers a broad spectrum of tools with very different purposes. Static analysis catches vulnerabilities in code before it ships. Dynamic testing probes running applications from the outside. Interactive testing instruments the application from within. Penetration testing frameworks simulate what an attacker actually does once they’re inside. Choosing the wrong category for your problem doesn’t just leave gaps, it gives your team false confidence that the surface is covered when it isn’t.

The market has also split on delivery model. Platforms like Aikido and Invicti aim for consolidation, pulling multiple testing methods into a single workflow. Specialist tools like Burp Suite and Metasploit go deep in a single discipline, trading breadth for the granular control that professional testers need. Open source options like ZAP and Metasploit remove licensing cost entirely, with trade-offs in automation depth and vendor support. Most mature AppSec programs end up running more than one.

We evaluated application security testing tools across detection accuracy, integration depth with CI/CD pipelines and developer workflows, false positive rates, and the operational overhead of running each tool after initial setup. We also reviewed customer experiences across deployed implementations to identify where vendor claims diverge from what security teams encounter in practice.

This guide gives you the criteria and decision logic to match the right application security testing tools to your environment, your team’s technical maturity, and the specific attack surface you need to cover.

What is Application Security?

Security testing is the process of checking applications and infrastructure for weaknesses that an attacker could exploit, before an attacker finds them. It covers several different methods, from automated tools that scan your code or your live website for known flaws, to manual penetration testing where a skilled tester tries to break in the way a real attacker would. The goal is the same across all of them: find the holes, prove which ones actually matter, and fix them before they cause a breach. Most organizations use more than one method because each catches different problems.

Security testing spans a set of complementary disciplines. Static Application Security Testing (SAST) analyzes source code without running it, catching flaws at the point of introduction. Dynamic Application Security Testing (DAST) probes a running application from the outside with no access to source, surfacing issues only visible at runtime. Interactive Application Security Testing (IAST) instruments the application from within to combine both views. Penetration testing and adversary simulation frameworks go further, chaining exploits to demonstrate real-world impact and validate which findings are truly exploitable.
These methods map to different points in the lifecycle and different threat models. SAST and DAST embed into CI/CD pipelines for continuous coverage, while pen testing and red team tooling validate defenses against an active adversary. Mature programs layer them: scanners for breadth and speed, manual testing for depth and exploit validation. Detection accuracy, false positive rates, and how cleanly findings route to the developers who fix them determine whether a tool earns its place in the workflow.

Astra Security Pentest

Astra Security Pentest Logo
Astra Security

Best for Teams preparing for compliance certification

Astra combines automated DAST scanning with managed manual penetration testing on the same platform, targeting web apps, APIs, PWAs, and SPAs. We think it sits in a useful middle ground: more structured than a pure scanner, lighter than a full red team engagement, and well-suited for teams preparing for compliance certification.

  • Scanner runs over 9,300 checks covering OWASP Top 10, SANS 25, and known CVEs
  • Over 10,000 authenticated attack cases for API testing specifically
  • Authenticated scanning works via a browser extension that records login flows, reaching vulnerabilities hidden behind login screens
  • Compliance reporting maps findings to ISO 27001, HIPAA, SOC 2, GDPR, and PCI DSS inside a built-in Resolution Center
  • Pentest Plan includes a publicly verifiable security certificate that auditors and partners can check independently

Customers say the dashboard makes triage straightforward, and the collaborative remediation approach stands out. The support team earns specific praise for helping harden infrastructure broadly, not just chasing individual ticket closures. According to customer feedback, retest scope gets unclear when distinguishing a reopened finding from a new surface, and remediation guidance is text-based only with no visual walkthroughs.

We think Astra is a good fit for teams that want a structured pentest process with ongoing support, not just a report to file. If you need external validation with clear findings ahead of a compliance audit, the combination of automated scanning, manual testing, and built-in compliance checks reduces the tooling overhead of audit preparation. Manual retest runs are limited, so scope your engagements carefully before kickoff.

Strengths
Combines automated DAST with managed manual penetration testing on one platform
Over 9,300 scanner checks plus 10,000+ authenticated API attack cases
Compliance reporting for ISO 27001, HIPAA, SOC 2, GDPR, and PCI DSS built in
Publicly verifiable security certificate included with Pentest Plan
Collaborative support focused on infrastructure hardening, not just ticket closure
Cautions
Manual retest runs are limited, requiring careful upfront scoping
Customers note remediation guidance is text-based only, no visual walkthroughs
4.

Fortra Cobalt Strike

Fortra Cobalt Strike Logo
Fortra

Best for Mature red teams running structured APT emulation

Cobalt Strike is an adversary simulation platform built for red team operations and advanced penetration testing. It replicates the long-dwell, stealthy behaviors of sophisticated threat actors inside enterprise networks, and we think it remains the standard framework for organizations running structured APT emulation programs.

  • Beacon payload acts as a post-exploitation agent designed to maintain persistent access while evading detection, using asynchronous low and slow communication and a malleable command and control language
  • Shared team server model supports multi-operator red team engagements where several testers coordinate and document post-exploitation activity in real time
  • Community Kit and custom scripting API let teams tailor capabilities and keep simulations current as threat actor techniques evolve
  • Version 4.12 added a refreshed GUI, a REST API, user-defined C2 channels, and new process injection options

Beacon functionality earns consistent praise from red teamers, and the built-in modules cover a full range of post-exploitation scenarios across the attack lifecycle. Some users report that pricing is a significant consideration, particularly for non-US teams. The cost reflects enterprise positioning but places Cobalt Strike out of reach for smaller security teams or those on restricted budgets.

We think Cobalt Strike is the right call for mature red teams running structured adversary simulation programs against enterprise environments. If your organization needs credible APT emulation with collaborative multi-operator support, this is built for that purpose. For teams earlier in their red team program, the cost and operational complexity are harder to justify. The capability is substantial; the question is whether your program is ready to fully use it.

Strengths
Beacon payload delivers realistic APT emulation with persistent, stealthy access
Shared team server enables multi-operator collaboration with full activity documentation
Community Kit and scripting API allow custom extension development
Version 4.12 adds REST API, user-defined C2 channels, and updated process injection
Cautions
Users flag pricing as high, particularly for non-US teams
Requires an experienced red team to extract full value
5.

Invicti Application Security Testing

Invicti Application Security Testing Logo
Invicti

Best for Enterprise teams needing continuous DAST across a large web portfolio

Invicti is an enterprise DAST and IAST platform for continuous web application and API security testing. Born from the Netsparker scanner, the platform scales from single-site scans to enterprise-wide security programs covering thousands of web assets.

Portswigger Burp Suite

Portswigger Burp Suite Logo
PortSwigger

Best for Professional manual and semi-automated web app pen testing

Burp Suite is the standard tool for manual and semi-automated web application penetration testing. We think it’s near-mandatory for any team running professional web app security testing. It’s built for security testers who need granular control over HTTP traffic, not teams looking for an automated scanner to run in the background.

  • Intercepting proxy sits between your browser and the target, letting you inspect, modify, and replay requests in real time
  • Repeater handles manual payload testing while Intruder automates parameter fuzzing, together effective for mapping application logic flaws
  • Burp Suite Professional adds JavaScript-heavy app and API scanning
  • Out-of-band application security testing (OAST) catches vulnerabilities that produce no visible response
  • WAF-aware false positive filtering
  • BApp extension library and custom extension API let teams build capabilities specific to their testing workflows

Customers describe Burp Suite as their daily driver for web app, API, and mobile dynamic testing. The extension ecosystem earns consistent praise for expanding core capabilities beyond what ships out of the box. Some users report that the jump from free Community Edition to Professional is steep, particularly for individual researchers. Per-user licensing adds up fast for larger teams, and the interface can feel cluttered across multiple tabs with a real learning curve for new users.

We think any team running manual web application security testing needs Burp Suite in their toolkit. If your organization has professional pentesters or runs a bug bounty program, the Professional license pays for itself quickly. For teams expecting automated coverage out of the box, set expectations accordingly. Burp rewards experience and grows with your team over time.

Strengths
Intercepting proxy gives testers complete real-time control over HTTP traffic
Repeater and Intruder cover manual payload testing and automated parameter fuzzing
OAST detects vulnerabilities that produce no visible application response
BApp extension library and custom API let teams tailor the tool to specific workflows
Free Community Edition provides a meaningful entry point
Cautions
Professional license pricing is a significant jump from free
Users report the interface becomes cluttered, with a steep initial learning curve
7.

Probely

Probely Logo
Probely

Best for DevSecOps teams with significant API surface area

Probely is a cloud-based DAST platform for DevSecOps teams running automated web application and API security testing inside CI/CD pipelines. It was acquired by Snyk in November 2024 and is now also available as Snyk DAST, though the Probely brand continues to operate. We think the API scanning depth and zero false positive approach make it a strong option for teams with significant API surface area.

  • Scanner replicates human browsing behavior, clicking through pages, filling forms, and following JavaScript-driven interactions
  • Broad API coverage handles RESTful APIs, follows XHR requests in SPAs, and accepts OpenAPI/Swagger schemas or Postman Collections for standalone API scanning, with 115 vulnerability types specific to APIs
  • Authenticated scanning supports SSO and OpenID Connect
  • Compliance reporting covers PCI-DSS, SOC 2, HIPAA, ISO 27001, and GDPR
  • Agent-based scanning enables testing of internal applications behind firewalls without opening inbound ports

Customers say Probely integrates cleanly into CI/CD pipelines and connects well with Jira and Slack. Scanning accuracy is consistently highlighted, and implementation earns positive marks from technically proficient teams. Based on customer reviews, pricing draws the most criticism regardless of organization size. Customers also flag that concurrent scanning is limited to a single scan at a time, creating bottlenecks in larger environments.

We think Probely is a solid fit for DevSecOps teams running modern app stacks with significant API surface area. If your pipeline needs accurate, automated security testing with broad compliance reporting, the platform delivers. Validate the single concurrent scan limitation against your scanning volume before committing. For teams with focused application estates and API-heavy workflows, it earns its place in the pipeline.

Strengths
Zero false positive approach with ML-based evidence verification reduces triage time
Broad API scanning covers RESTful, GraphQL, OpenAPI/Swagger, and Postman Collections
Authenticated scanning with SSO and OpenID Connect covers all surfaces
Agent-based scanning tests internal apps behind firewalls

Concurrent scanning limited to one scan at a time, creating bottlenecks at scale
8.

Rapid7 Metasploit

Rapid7 Metasploit Logo
Rapid7

Best for Teams validating vulnerabilities through actual exploitation

Metasploit is the most widely adopted open-source penetration testing framework in the industry. We think it remains a foundational tool for any team running structured pentest programs that need a proven, well-documented framework with broad exploit coverage and the ability to demonstrate real-world vulnerability impact to business stakeholders.

  • Core strength is its exploit database, with over 2,074 exploits organized across platforms including Windows, Linux, macOS, Android, and Cisco
  • Teams can customize payloads across multiple formats and tailor them to specific engagement requirements
  • Metasploit Pro adds Quick Start Wizards, social engineering campaign management, web application testing, and anti-virus evasion with dynamic payloads
  • InsightVM integration connects vulnerability scanning directly to exploitation validation, tightening the loop between discovery and proof of impact

Customers describe Metasploit as a full toolkit for penetration testing rather than a dedicated scanner. The interface earns specific praise for live demonstration scenarios where showing a non-technical audience an exploit executing in real time carries more weight than a written report. Some users report that installation is complex and the learning curve for beginners is steep. Some offensive security professionals prefer custom tooling, viewing Metasploit as better suited to structured engagements than advanced bespoke red team work.

We think Metasploit suits security teams that need to validate vulnerabilities through actual exploitation and demonstrate impact to leadership. The workflow from exploitation to live demonstration is hard to match. For advanced red team operators who rely on custom tooling, Metasploit may feel constraining. For everyone else running formal pentest programs, it’s a foundational capability that earns its place in the toolkit.

Strengths
Over 2,074 exploits across Windows, Linux, macOS, Android, and Cisco platforms
InsightVM integration connects scanning directly to exploitation validation
Live exploit demonstrations carry real weight with non-technical stakeholders
Metasploit Pro adds social engineering campaigns, web app testing, and AV evasion
Free open-source framework with broad community support
Cautions
Installation is complex, with a steep learning curve for new practitioners
Customers note it's viewed as limited for advanced bespoke red team operations
9.

Tenable Nessus

Tenable Nessus Logo
Tenable

Best for Mature programs scanning large, diverse asset inventories

Nessus is a vulnerability scanner built for broad attack surface coverage across endpoints, servers, web applications, cloud infrastructure, and internet-connected assets. We think it’s the right choice for mature security programs scanning large, diverse asset inventories where compliance reporting and structured vulnerability tracking sit alongside scanning in the same workflow.

  • Uses dynamically compiled plugins to speed up scan performance and reduce time to initial results
  • Plugin library covers nearly 300,000 plugins with 113,000+ CVEs and a 0.32% false positive rate
  • Over 450 pre-configured templates cover a wide range of use cases out of the box
  • Live Results assesses vulnerabilities offline with every plugin update without requiring a full rescan
  • Groups similar issues automatically for prioritization, with a snooze feature that sets aside lower-priority findings for defined periods

Customers say Nessus handles large-scale asset scanning quickly and accurately across mixed environments. The remediation tracking capability earns specific mention, particularly the ability to create remediation projects and assign vulnerability ownership to teams. Some customer reviews note that support quality is inconsistent, with responsiveness gaps flagged by multiple users. Dashboard customization carries a meaningful learning curve, and policy changes and predefined compliance values have limited configuration flexibility.

We were impressed by the speed and accuracy Nessus delivers at scale. If your team manages endpoints and infrastructure across a large, mixed environment and needs compliance reporting alongside structured vulnerability tracking, Nessus is well worth considering. Build in time to learn the dashboard configuration. Once your team is comfortable, the workflow from scan to remediation assignment runs efficiently.

Strengths
Nearly 300,000 plugins with 113,000+ CVE coverage and a 0.32% false positive rate
Live Results runs offline vulnerability assessments with every plugin update
450+ pre-configured templates for broad out-of-the-box coverage
Remediation project assignment tracks vulnerability ownership across teams
Snooze feature keeps dashboards focused on what needs immediate attention
Cautions

10.

Zed Attack Proxy (ZAP)

Zed Attack Proxy (ZAP) Logo
Checkmarx

Best for Teams building an AppSec program on a budget

ZAP is a free, open-source web application security scanner that sits in the Checkmarx portfolio following its move from OWASP to the Linux Foundation in 2023 and the core team joining Checkmarx in 2024. We think it’s the right starting point for teams building an AppSec program on a budget, and it delivers real capability at zero cost.

  • Operates as a man-in-the-middle proxy, intercepting and manipulating HTTP and HTTPS traffic during testing
  • Active and passive scanning modes: passive scanning observes traffic without sending attack payloads, while active scanning probes for vulnerabilities directly
  • AJAX spider and fuzzing capabilities extend automated coverage to modern JavaScript-heavy apps
  • Scan policy configuration lets teams run different scenarios against different targets
  • Extension marketplace adds capabilities without switching tools, and scripts can customize behavior and reduce false positive rates

Customers consistently highlight zero cost as a major differentiator, alongside easy installation and cross-platform support. The AJAX spider earns strong feedback from users building security testing into development workflows. Some users report that false positives are the main operational friction, requiring manual verification and extra configuration to reduce noise. Customers also note that ZAP lacks a built-in browser, which is available in commercial alternatives, and that automated feature depth trails newer paid tools.

We think any team that needs capable web application security testing without commercial tooling costs should start with ZAP. It’s a strong foundation for pipeline scanning and manual testing alike. For enterprise programs that need advanced automation, fewer false positives, and dedicated vendor support, the open-source model has real trade-offs. But for teams building from scratch, ZAP delivers serious capability without a licensing conversation.

Strengths
Free and open source with no licensing cost or user restrictions
Active and passive scanning modes with customizable scan policies per target
AJAX spider and fuzzing extend automated coverage to complex JavaScript apps
Cross-platform support with no dependency on a specific OS environment
Extension marketplace expands capabilities as needs grow
Cautions
Reviews mention false positives require manual verification and script-based tuning
No built-in browser, a capability available in commercial alternatives

Application Security Checklist

These are the questions and operational steps we recommend working through when selecting and combining security testing tools, whichever vendors you choose.

SAST, DAST, IAST, and pen testing each catch different flaws, so picking the wrong category leaves gaps while giving false confidence that the surface is covered.

Scanners give breadth and speed while manual testing gives depth and exploit validation; mature programs layer them rather than relying on a single tool.

A tool that buries developers in noise erodes trust fast, so validate the signal-to-noise ratio against your real applications, not a vendor demo.

Findings that surface where developers already work get fixed faster than reports filed after the fact.

Many of the highest-impact vulnerabilities sit behind login screens or in API endpoints that unauthenticated scans never reach.

Regulated environments often need on-premises or agent-based scanning so source code and traffic never leave your network.

Built-in mapping to OWASP Top 10, ISO 27001, SOC 2, PCI DSS, or HIPAA turns audit preparation from a manual exercise into an export.

Proof-based scanning or exploitation frameworks show which findings are truly exploitable, which carries far more weight with leadership than a raw vulnerability count.

Tools like ZAP and Metasploit remove licensing cost but trade away automation depth and dedicated support, which matters as programs scale.

Tuning, triage, and concurrent-scan limits drive the real cost of ownership, so factor ongoing effort into the decision, not just the license fee.

The Bottom Line

Your application security testing decision depends on what you’re trying to cover, who’s doing the testing, and where in the development lifecycle you need findings to surface.

For teams building DevSecOps programs from scratch, SonarQube handles static analysis and CI/CD gate enforcement, while ZAP adds dynamic scanning at zero additional cost. That combination covers the fundamentals before you commit to paid tooling. As your program matures, Aikido’s consolidated platform reduces tool sprawl for SMB and mid-market teams that need code-to-cloud visibility without managing multiple products.

For dynamic testing at enterprise scale, Invicti’s combined DAST and IAST approach with Proof-Based Scanning reduces the false positive triage that slows developer teams down. Probely suits API-heavy modern app stacks where accurate automated scanning inside the pipeline matters more than broad feature depth.

Professional penetration testers need Burp Suite. That’s the short version. Teams running structured pentest programs that need a documented, repeatable framework should evaluate Metasploit alongside it. For organizations running adversary simulation programs against enterprise environments, Cobalt Strike is built for that purpose, provided your red team has the experience to use it effectively.

For teams preparing for compliance certification, Astra’s combination of automated scanning, manual testing, and built-in compliance checks for ISO 27001, HIPAA, SOC2, and GDPR reduces the tooling overhead of audit preparation. Nessus suits mature vulnerability management programs scanning large, mixed-asset inventories where remediation tracking and compliance reporting sit alongside scanning in the same workflow.

The wrong choice leaves coverage gaps your team doesn’t know exist. The right combination catches vulnerabilities early, integrates into the workflows developers already use, and gives your security program evidence of effectiveness when regulators or leadership ask for it.

Everything You Need To Know About Security Testing Tools (FAQs)

Security testing tools support the identification of vulnerabilities and make it easier to accurately assess weak points and evaluate the overall security posture of software applications, systems, or networks. These tools are highly useful for maintaining strong cybersecurity and are used by security professionals, and developers  to identify and address possible security risks proactively.

It is important to be aware that security testing is not a one-size-fits-all kind of process, and the effectiveness of any security testing tool you consider implementing will vary considerable depending on a number of factors. These include what type of systems are being tested, which testing methodology is being used, and the level of skill and expertise of the security professionals that are carrying out the assessment. In addition, while security testing tools are highly useful and play an important role in maintaining strong security, a truly through assessment would also benefit from the insight of skill security experts who perform manual penetration testing.

Security testing tools essentially work in two ways. Firstly, they scan, identify, and report potential security vulnerabilities. Secondly, they provide recommendations and solutions to fix these weaknesses and improve your overall security posture. Security testing tools provide both automated and manual testing processes to facilitate vulnerability remediation.

The use of security testing tools provides a variety of benefits to organizations, which including;

  • Better identification of possible vulnerabilities
  • Proactive mitigation or risk
  • Cost effective security assessment
  • Continual improvement to security
  • Compliance assurance
  • Easier measurement of security effectiveness
  • Speedy detection and response
  • Improved reputation with customers

Essentially, these tools are worth utilizing to build a resilient cybersecurity strategy and to face constantly evolving cyber threats head on.

Security testing tools many vary significantly between vendors, but some particularly useful capabilities you may want to look out for include the following:

  • Vulnerability assessment: The ability to scan and identify a range of vulnerabilities in a target system is absolutely essential,. This function generally involves assessing the environment based on a list of potential vulnerabilities, such as system misconfiguration, out of date software, and malware. Typically, a combination of tools – like Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Network Vulnerability Scanners – will work together to achieve this.
  • Penetration Testing: This is a security testing methodology that involves simulating real-world cyber-attacks in a controlled environment in order to assess whether security measures are resilient, and to discover any unidentified weak points. Many security testing tools provide penetration testing as part of their feature sets, and this feature is a useful one for organizations looking to gain a realistic and thorough assessment of their security defenses.
  • Reporting and remediation: A good security testing tool should be capable of providing detailed and accurate reports that clearly and concisely outline the vulnerabilities and possible risks that have been identified, as well as provide actionable remediation guidance.
  • Easy integration and automation: Integrations with third-party tools facilitate a more holistic approach to security, while automations streamline the testing process and make it quicker and easier to respond to security findings. A good security testing tool should support integration with automation tools, SIEM solutions, and vulnerability management systems.
  • Continual monitoring and testing: Applications and security threats are always evolving, so any vulnerability and security testing solutions need to be continuous and adaptable to changes and new security risks. A good security testing tool should provide continuous or periodic testing and monitoring in order to properly assess and respond to security threats in an ongoing manner.
