We are impressed by IRONSCALES. The platform is constantly adding new features, like email spam filtering, encryption, and deepfake protection. The core of the product is the crowdsourced threat intelligence built on end-user email reporting, which is an effective way of blocking phishing, alongside powerful threat protection engines. If you are looking for effective post-delivery phishing protection with built-in awareness training, IRONSCALES delivers. The free Starter tier offers phishing simulation and testing for up to 500 mailboxes, though full email protection requires a paid plan.

• Phish Protect feature provides a high-confidence phish score scanning for DMARC failure, impersonation patterns, and suspicious email content for multi-layered phishing detection.
• Customizable banners on external senders, suspected impersonation attempts, and other risky messages with banner customization above competitive platforms.
• Quarantine digest report rounds up suspicious emails with user self-service release without contacting the helpdesk.
• Three deployment options: MX-based gateway, API-only for Microsoft 365, and combined gateway-plus-API mode.

Bitdefender is a good choice for MSPs looking for strong protection against phishing, but also a more rounded platform for addressing email security risk. There are multiple layers of security with warning banners, and strong policy controls that can be applied across all of your customer environments. Detection is signal and rule-based rather than behavioral, which keeps false positives low. The commercials are strong for MSPs, with cost-effective single-SKU pricing at a competitive price point.

• Inbox-level MFA locks down sensitive messages and password reset emails if an account gets hijacked, preventing attackers from using them.
• Bulk email removal pulls threats from all mailboxes in seconds.
• Deploys in about 30 minutes via API with no MX record changes required.
• Google Workspace treated as a first-class integration, not a bolt-on.

Customers say Material treats Google Workspace as a true first-class environment, not an afterthought. Support consistently gets top marks, with teams praising fast response times and a willingness to work through complex deployment scenarios. Something to be aware of is that initial setup can feel overwhelming for less experienced teams, and the ticketing dashboard needs UX improvements.

We think Material is well worth considering for teams that want more than phishing filtering. If you need inbox-level data protection and identity controls alongside detection, this covers ground most other platforms don’t.

• Analyzes thousands of signals to baseline normal communication patterns and flag anomalies.
• One-click API deployment with no disruption to mail flow.
• Malicious messages pulled automatically before users interact with them.
• Detection extends beyond email to calendar invites, collaboration tools, and identity signals.

Customers say the accuracy stands out immediately, with teams reporting a significant drop in phishing triage time after switching from legacy gateways. The low false positive rate is a consistent theme. Something to be aware of is that reporting filters don’t persist between views, and role-based access controls lack granularity for larger teams.

We think Abnormal AI is well worth considering if your priority is detection accuracy with minimal operational overhead. The behavioral AI catches attacks that signature-based tools miss entirely, and the low false positive rate means less wasted analyst time.

• Dynamic, color-coded warning banners flag suspicious messages in context, coaching users at the moment they need it.
• Evaluates links, language, sender reputation, attachments, and QR codes together for multi-signal detection.
• One-click remediation removes malicious emails across all affected mailboxes.
• Per-user risk scoring identifies the most vulnerable users for targeted training.

Customers highlight strong support and easy initial setup. The Outlook integration works well, though some users note it can add a slight delay to sending and startup. Something to be aware of is that coaching banners need internal communication before rollout so users understand what they’re seeing. The platform is M365 only.

We think KnowBe4 Defend is well worth considering if your biggest concern is user-driven phishing risk. The real-time coaching approach reduces click rates while building security awareness, which sets it apart from tools that only filter threats silently.

• Targeted rules catch domain spoofing and display name impersonation with specific actions per policy.
• Active Directory sync flags messages where the display name matches an employee but the sender is external.
• Analyst-backed threat hunting adds human intelligence to automated detection.
• Supports M365, Exchange, and Google Workspace for multi-platform deployment.

Customers say message analytics are informative without being overwhelming, and the platform catches threats primary gateways miss. The ability to remediate harmful emails directly from user mailboxes gets positive marks. Something to be aware of is that policy exception workflows need improvement, and feature development pace has slowed in recent releases.

We think Fortra’s Cloud Email Protection is a good option to consider if you need flexible deployment across M365, Exchange, and Google Workspace. The policy customization suits teams that want granular control over impersonation detection rules.

• Fraud forensics engine analyzes identity spoofing, malicious intent, falsified facts, and espionage patterns beyond signature-based detection.
• Built-in sandbox detonates suspicious attachments and decrypts weaponized documents.
• URL rewriting replaces links in real time before users click.
• Now backed by Proofpoint following the December 2025 acquisition.

Customers say centralized control saves significant admin time, and the AI analysis is practical for quickly assessing email risk without manually reviewing each message. Something to be aware of is that the Fraud Forensics module can over-block with limited rule customization, and initial setup requires more groundwork than expected.

We think Hornetsecurity is a good option to consider if you want layered detection with sandboxing and AI forensics in one package. The Proofpoint acquisition adds enterprise credibility and should extend the platform’s reach.

• Safe Links rewrites URLs at click time and Safe Attachments detonates suspicious files in a sandbox.
• Automated Investigation and Response reduces manual triage by correlating alerts and taking action automatically.
• Teams message protection flags known malicious URLs at delivery and retroactively up to 48 hours later.
• AI-powered submissions response uses generative AI to explain email verdicts to administrators.
• Built-in protection policies apply Safe Links and Safe Attachments to all users by default.

Customers say the dashboards make daily incident management efficient, and threat analysis reports help teams understand what’s hitting their environment. Something to be aware of is that policy configuration complexity can overwhelm newer administrators, and support response times are reported as slow for urgent security issues.

We think Defender makes sense as a baseline for organizations already invested in the Microsoft stack. The native integration is hard to beat, and you avoid adding another vendor. If you need granular policy control or support for non-Microsoft environments, consider whether a supplementary or dedicated platform is needed.

• Impersonation Protection accurately flags BEC and CEO fraud attempts.
• URL rewriting scans links in real time across live and archived emails, extending to URLs in archived messages to prevent delayed attacks.
• Suspicious attachments are sandboxed before delivery so malicious files never reach your system.
• Scans all inbound emails in real time for key indicators in header, domain, and email content.
• Now connects with 350+ security vendors following the March 2026 update.

Customers say protection is consistent and low-noise, with strong phishing and impersonation blocking out of the box. Policy customization runs deep, giving teams granular control. Something to be aware of is that the admin interface can feel clunky with deeply nested settings, and URL rewriting occasionally breaks legitimate links.

We think Mimecast is well worth considering if you need phishing protection that works across cloud, hybrid, and on-premises setups. The policy depth suits teams that want fine-grained control, and the easy-to-read reports and analytics, combined with a high level of flexibility and customization, make it a strong solution for mid-sized and enterprise organizations.

• NexusAI detects payload-less BEC by analyzing behavior, language, and headers beyond traditional signature-based approaches.
• Multilayered detection stacks IP reputation, machine learning, and dynamic classification to filter spam, phishing, and bulk mail.
• Color-coded warning tags on suspicious messages coach users in real time.
• URL Defense and Attachment Defense detect, catch, and sandbox malicious URLs and attachments.
• Customizable policies at user, group, and global level support complex environments.
• Supports cloud, on-premises, virtual appliance, and hybrid deployments.

Customers highlight strong detection accuracy and behavioral analytics that catch anomalies traditional tools miss. Teams using the DLP modules praise visibility into user behavior. Something to be aware of is that initial policy setup requires significant tuning, and the full platform value requires multi-module adoption, which increases cost and overhead.

We think Proofpoint Core Email Protection is well worth considering if your organization operates at scale with complex infrastructure and compliance requirements. The cost-effective way in which Proofpoint wraps their features into one manageable package makes it a strong option for organizations across all sectors. If you’re a smaller organization, Proofpoint also offers their 365 Total Protection bundle (formerly Proofpoint Essentials) tailored to SMB needs.

• Machine learning analyzes communication patterns to detect impersonation and fraudulent messages, catching phishing, malware, and suspicious links before they reach inboxes.
• API deployment in minutes with no MX record changes.
• Flow-level visibility tracks file and message movement across collaboration tools, supporting audit requirements.
• Runs quietly in the background with minimal impact on daily workflows.

Customers say the platform works quietly in the background without adding friction to daily workflows. The M365 and Gmail integration gets consistent praise for being low-maintenance once deployed. Something to be aware of is that filtering can be overly strict, quarantining legitimate emails at times, and policy customization lacks granularity across user groups.

We think Check Point Email Security is well worth considering if you need protection extending beyond email into collaboration tools. If your organization runs M365 or Google Workspace with heavy file sharing in Teams, OneDrive, or Google Drive, the collaboration coverage adds value that email-only tools miss.
