For MSPs and lean IT teams who need serious threat detection without building out a SOC, Huntress 24/7 SOC catches early BEC indicators like mailbox tampering and OAuth abuse. Microsoft Defender XDR management still maturing
If you’re looking for a solution that makes full use of Agentic AI to guide remediation, Material Security is your solution.
If you need organizations with this need, Abnormal AI API integration deploys in minutes with no mail flow changes required. Post-delivery model means some threats land before remediation
Business email compromise looks deceptively simple: an attacker impersonates a trusted sender and requests money or sensitive data. In reality, BEC attacks exploit every weakness in your email security, identity controls, and human judgment all at once.
The right BEC solution detects what traditional email gateways miss: subtle changes in communication patterns, unauthorized OAuth apps, credential phishing, and supply chain fraud. You need something that integrates with your existing email and identity infrastructure without creating alert fatigue, catches the attacks that slip past native Microsoft or Google protections, and gives your team actionable insights to respond fast when something looks wrong.
We evaluated multiple BEC and email security platforms across detection accuracy, integration depth, alert quality, user experience, and support responsiveness. We assessed how well each handles identity-layer threats, behavioral anomalies, and the specific attacks that bypass signature-based filtering. This guide gives you the decision criteria and vendor comparisons to match BEC protection to your team size, existing infrastructure, and security maturity.
Your ideal platform depends on your specific deployment requirements and which capabilities matter most.
Huntress is a fully managed security platform built for MSPs and lean IT teams who need serious threat detection without building out a SOC. The 24/7 human-backed response team focuses heavily on credential theft and application abuse, making it particularly effective against business email compromise.
We found the Microsoft 365 monitoring catches the subtle stuff attackers rely on: suspicious mailbox rule changes, MFA fatigue attempts, and unauthorized OAuth apps. These are the early warning signs that often slip past traditional tools.
The managed EDR component ties endpoint telemetry back to identity events. If a device looks compromised, the SOC flags accounts that need lockdown. We saw incident summaries that gave clear remediation steps without the noise you get from other platforms.
Users consistently praise the lightweight deployment and RMM/PSA integrations. Install is quick, admin overhead stays low. The SOC team gets high marks for response speed and clear communication.
We think Huntress hits a sweet spot if your team lacks dedicated security analysts but needs identity-layer visibility across Microsoft 365 and endpoints. The price-to-value ratio works well for organizations that want managed detection without enterprise complexity.
If you need advanced XDR customization or already run a mature SOC, this probably isn’t your tool. But for MSPs and IT teams who want someone watching the wire around the clock, it delivers.
Material Security is a cloud workspace security platform for Google Workspace and Microsoft 365 that goes beyond the email perimeter. It addresses the full scope of the BEC problem: detecting and blocking inbound attacks, locking down the sensitive data attackers are trying to reach, and containing compromised accounts before they can be weaponized.
Detection And Response For The Full Cloud Workspace
Material uses a custom rules engine, agentic automation and LLM analysis to stop inbound email threats, including VIP impersonation and credential phishing attempts.
Beyond inbound detection, Material also locks down email content within the inbox, meaning that if an account is compromised, data like sensitive attachments, OTPs, or password reset links remain protected. This matters for BEC specifically: an attacker who gains access to a mailbox can do significant damage before anyone notices. Material significantly limits what they can reach.
File security permissions controls and identity security controls extend that containment logic across the workspace, restricting what a compromised account can actually do inside Google Workspace and Microsoft 365. The platform also provides cloud workspace posture management and OAuth app remediation to identify and revoke suspicious third-party tokens, a common and underappreciated vector in account takeover scenarios that enable BEC.
What Security Teams Say
Material’s account compromise containment is very effective at slowing attacks and limiting the amount of data that can be accessed during a breach, according to user reviews. Users also highlight that Material makes incident analysis a lot faster.
Reporting is straightforward, and users praise the pace of new feature releases and the responsiveness of the support team. Some customers do say that rules configuration can be challenging without in-house email security experience, but note that the Material support team is responsive.
Our Take
BEC is particularly hard to stop because it doesn’t always look like an attack — it looks like a legitimate email from a trusted source. Material addresses this at multiple levels: catching the impersonation attempts and credential phishing that typically precede account takeover, locking down the sensitive content that makes a compromised account dangerous, and applying identity controls that limit what an attacker can do even if they get in. It’s a more complete answer to BEC than tools that focus on blocking inbound messages alone.
If your team is looking for a platform that treats BEC as the multi-stage problem it actually is, this is a strong solution to consider.
Abnormal AI is an API-based email security platform that skips the traditional secure email gateway model entirely. It connects directly to Microsoft 365, learns normal communication patterns, and catches the social engineering attacks that rule-based filters miss.
We found the behavioral approach works well for stopping BEC, supply chain fraud, and credential phishing. The platform baselines how your people actually communicate, then flags anomalies. No signatures, no constant tuning.
Setup takes minutes through API integration. We saw detection accuracy stay high without the policy tweaking that legacy gateways demand. The machine learning improves over time as users report false positives and negatives back into the system.
Abnormal ingests signals from Slack, Active Directory, and other Microsoft 365 services to build richer user profiles. This cross-platform visibility helps catch account takeover attempts that email-only tools would miss.
The analytics dashboard surfaces security posture gaps and automates compliance reporting. It consolidates threat intelligence into a single view rather than forcing you to pivot between tools.
The post-delivery model has a timing limitation. Outlook sometimes processes malicious calendar invites before Abnormal can delete them. You may need to adjust default Outlook settings to close that gap.
Some users want better tooling for reviewing and releasing held messages.
We think Abnormal fits organizations tired of tuning gateway rules who want behavioral detection that just runs. The set-and-forget model appeals to lean security teams.
Avanan is an API-based email security layer that sits behind your existing defenses to catch what Microsoft Defender and Google’s native tools miss. Now part of Check Point (branded as Harmony Email), it focuses on BEC, phishing, and account compromise across Microsoft 365, Google Workspace, Slack, and Dropbox.
The platform deploys via API with no MX record changes. It builds behavioral profiles from communication patterns, employee relationships, and historical email data. Smart-Phish, their anti-phishing engine, uses this context to spot impersonation attempts that signature-based tools overlook.
We found the layered approach makes sense for organizations already running Defender or Proofpoint but still seeing phishing slip through. Avanan analyzes inline rather than replacing your gateway, filling gaps without forcing an architecture overhaul.
Beyond email scanning, Avanan monitors for suspicious activity across your cloud apps. Unrecognized logins, repeated password resets, and anomalous behavior trigger alerts. You can configure automatic lockout policies to contain compromised accounts before damage spreads.
Real-time reporting gives your team visibility into threat details and attack patterns. This helps with both incident response and understanding where your exposure sits.
Users report significant drops in phishing reaching inboxes. Some cite 90%+ reductions after deployment. The API install is quick, typically same-day activation with immediate visibility.
The main gap customers mention is mobile access.
We think Avanan works best as a second layer when native Microsoft or Google protections are not cutting it. If you are building a new stack from scratch, a full-featured SEG might make more sense.
Cofense combines phishing simulation, security awareness training, and automated threat response into one platform. It turns your employees into active sensors while giving your SOC the tools to triage and quarantine reported threats fast.
The training component teaches employees to spot phishing and BEC attempts through interactive courses. You then test retention with simulated attacks that mimic real-world threats. When employees report suspicious emails through the reporting plugin, those reports feed directly into your security workflow.
We found this closed loop between training, testing, and reporting creates accountability.
The Phishing Defense Center analyzes reported emails and returns verdicts within an hour. That fast turnaround keeps employees engaged since they see their reports actually matter. You can write custom rules based on threats specific to your environment.
Automated quarantine capabilities let you contain confirmed threats based on your policies. The platform integrates with Microsoft 365 and Google Workspace without disrupting existing mail flow.
Email pull and quarantine require the Vision add-on. Competitors often include this as a baseline feature. If automated remediation matters to your workflow, factor that into licensing discussions.
Otherwise, feedback skews positive on reliability and flexibility. The platform scales across organization sizes without major configuration headaches.
We think Cofense fits organizations that want to invest in their human layer alongside technical controls. If your strategy depends on employees reporting threats accurately, the training-to-triage pipeline delivers.
Darktrace/Email uses self-learning AI to build behavioral baselines for every user in your organization. It detects anomalies in both inbound and outbound communications, catching threats that signature-based tools miss while reducing noise from spam and unwanted mail.
The platform learns what normal looks like for each employee, then flags deviations. This catches BEC, phishing, and supply chain attacks based on context rather than known indicators. We found the approach particularly effective for novel threats that have not hit threat intelligence feeds yet.
Darktrace extends beyond email to SaaS applications and network devices. This broader visibility lets it correlate suspicious email activity with other behavioral signals across your environment.
When Darktrace acts on a threat, it communicates directly with end users to explain why. Employees can provide feedback, which improves detection accuracy over time. This transparency helps reduce friction when legitimate emails get flagged.
The platform also filters productivity-killing noise like cold outreach, newsletters, and spam. Your team spends less time sorting through junk and more time on actual work.
Customers consistently flag pricing as a concern. Darktrace sits in the upper tier of the market. That said, users report you can negotiate, especially when bundling multiple modules from their portfolio.
Setup complexity comes up in feedback too.
We think Darktrace fits organizations that want AI-driven detection across email and their broader environment, not just a point solution. The self-learning model reduces tuning overhead once deployed.
IRONSCALES combines AI-powered email security with phishing simulation and security awareness training in a single platform. It protects against BEC, impersonation, invoice fraud, and supply chain attacks while building employee resilience through customized training modules.
The platform analyzes employee communication patterns, relationships, and habits to spot anomalies. This behavioral approach catches impersonation attempts and fraud that rule-based filters miss. Inbound filtering, URL scanning, DMARC enforcement, and anomaly detection work together across the threat chain.
We found the combination of technical controls and human intelligence creates a stronger defense than either alone. When the AI flags something suspicious, human analysts can validate and feed insights back into the system.
IRONSCALES delivers engaging training modules alongside customized phishing simulations. You can tailor simulation emails to match threats relevant to your industry and organization. This specificity makes training feel real rather than generic.
The platform integrates with Microsoft 365, Google Workspace, and Exchange without MX record changes. Deployment is fast, and users consistently praise how intuitive the interface is. Nothing important is buried or hard to find.
Customers flag one limitation: granular settings for different regions or groups require manual admin effort. If you run a large organization with varied policy requirements across locations, expect some configuration overhead.
The product team actively collects feedback on these gaps. Support is responsive and knowledgeable, which helps bridge the customization limitations.
We think IRONSCALES hits a sweet spot for SMBs and mid-market organizations that want email security and awareness training unified. The pricing stays accessible compared to enterprise-focused alternatives.
Proofpoint is the enterprise incumbent in email security, protecting over 8,000 organizations globally. Their Threat Protection Platform uses the Supernova detection engine to analyze billions of emails, URLs, and attachments daily, with Advanced BEC Defense as a core component.
The platform combines machine learning and AI to identify, block, and authenticate threats across the email chain. We found the detection capabilities hold up well against targeted attacks, supply chain compromise, and credential phishing. The scale of their threat intelligence network provides visibility that smaller vendors cannot match.
BEC-specific features include impersonation detection, supplier risk analysis, and user-specific threat data. Reporting goes deep, giving you granular insight into who is being targeted and how.
Daily digest emails with single-click actions save significant time. You can review flagged messages at a glance and approve or block without logging into the console. Users praise how intuitive the core workflows are.
The trade-off: Proofpoint has grown through acquisition, and it shows. Multiple admin consoles can make management feel fragmented. If you run a lean team, navigating between interfaces adds friction to your day.
The widespread adoption cuts both ways. When email issues arise between organizations, both sides often run Proofpoint, which simplifies troubleshooting. The community and documentation are strong.
Post-sale support gets mixed reviews. Some customers report the sales team disengages after implementation, leaving you to work through support channels for ongoing needs.
We think Proofpoint makes sense for mid-size to enterprise organizations that want proven detection at scale and can absorb the admin complexity. The threat intelligence depth is hard to replicate.
Barracuda offers a Total Email Protection portfolio, which provides all-inclusive protection against 13 different email threats, including spear phishing and Business Email Compromise (BEC)
Mimecast is a well-respected email security provider that offers a comprehensive, cloud-based security platform through a single subscription service.
When evaluating business email compromise solutions, we’ve identified six essential criteria. Here’s what you should be asking:
Weight these criteria based on your team size and infrastructure. MSPs and lean IT teams should prioritize managed detection and RMM integration. Organizations running mature SOCs want customization and deep threat intelligence. Teams already using native Microsoft or Google email protections should evaluate supplementary solutions that detect what built-in tools miss. Small organizations building email security from scratch benefit from consolidated platforms combining detection, training, and awareness.

BEC attacks use an authentic and trusted brand to trick victims into sharing sensitive details and information. They rely on accurate and authentic impersonation to make their requests seem more valid. For example, a user will be more likely to share financial details with a brand they already know and trust, than with someone unknown to them.
To make the attacks seem more legitimate, attackers will often try to gain access to an authentic inbox. This means that they are able to send email from a real email address, with the correct header, footer, and DKIM details. This reduces the amount of work they have to do in order to appear legitimate. It is for this reason that it is important for organizations to monitor the emails that are being sent from their inboxes as well as inbound messages.
Malicious actors are able to gain access to inboxes in a variety of ways. This includes using stolen credentials purchased on the dark web, previous phishing or social engineering attacks, and brute force attacks. So, the first thing you should do to prevent BEC attacks is keep your credentials safe. Some of the platforms features on this list are designed for this purpose.
Once they have gained access, an attacker will reach out from the compromised account to existing employees or to other companies. As they are writing from a valid email address, there is very little to raise the victims’ suspicions. The attacker may send a fake invoice, request access to data, or even attempt to hijack another account.
With the amount of information readily available online – think of all the information you share on LinkedIn – coupled with the valid account and ability to look back at previous conversations and imitate style, BEC can be a very effective and dangerous attack type.
To prevent BEC attacks, it is worth keeping an open mind about what to look for. With attackers constantly searching for new ways to trick you, is no checklist (or limit) to how they might try to fool you. Another area that could be worth investing in is Security Awareness Training (SAT) – this educates your users on suspicious behavior and explains best practice responses.
BEC attacks exploit the weakness of emails to target top-level people within an organization. Often BEC starts with a phishing attack which allows cyber-criminals to gain access to an important email account within an organization. For example, someone in the finance department, or the company CFO or CEO. Once attackers have access to this account, they can then send out emails that appear to be legitimate, asking for wire payments to be made from others in the organization, or across their supply chain. These emails won’t be flagged as malicious by any anti-virus or basic email filtering technologies, and most users probably won’t expect their boss or a trusted contact to be compromised, making this a particularly harmful kind of attack.
Another method cyber-criminals can use is simply spoofing the domains of high-level business email accounts. For example, the attacker will see the email address [email protected] and use [email protected] instead. This is known as Lookalike Domain Spoofing. The similarity of the email addresses may be enough to fool suspecting users into believing it’s the real contact that has emailed them, which could convince them to make a payment.
This type of BEC attack is less sophisticated than full account compromise, but it is much more common. It’s also much more likely to be stopped by email security technologies, as they can detect when a domain has been spoofed. However, it can still very successful in convincing unsuspecting users.
Lookalike domain spoofing is commonly used to impersonate brands, such as Microsoft or Apple. Attackers copy these brand domains to try and in convince users to enter passwords, or make payments.
We’ve broadly covered two methods in which attackers can carry out Business Email Compromise attacks, but the FBI has identified 5 unique variants of BEC. Here’s a brief rundown of what each involve:
CEO Fraud: Attackers impersonate a CEO, or a high-level executive, and target employees with requests for payments.
Account Compromise: An employee’s email account is compromised, and attackers use their contacts to request payments to their own accounts.
Bogus Invoice Schemes: Attackers will impersonate suppliers of foreign companies, in order to request fraudulent fund transfers and payments.
Data Theft: Employees in HR and admin departments are compromised so that attackers can gain access to sensitive company and customer information.
Attorney Impersonation: Attackers impersonate lawyers or solicitors to find out confidential business events. This is a sophisticated type of account compromise attack, and much less common.
Most industry analysts agree that BEC attacks are becoming more common because they are low risk for attackers, can be relatively low cost to pull off, and they are often very successful.
Rather than needing to spend time developing malware, or trying to gain access to systems, Business Email Compromise allows cyber criminals to very quickly get access to accounts and send out emails asking for payments. With just one compromised account, cyber criminals can send out hundreds of fraudulent emails, with a pretty good chance that at least one will be opened or replied to.
For high profile targets, cyber criminals may not even need to collect information for account compromise attacks themselves. High level employee email credentials are commonly bought and sold on the dark web. Research from LastLine tells us that CEO, CFO and executive account details fetch a high price, but attackers can make a profit of thousands by successfully mounting a business email compromise scam.
Traditional approaches to email security rely on detecting threats. This could be a malicious domain that’s been known to send out spam emails. Or, it could be an attachment that contains malware, or a URL that leads to a harmful website. Email security technologies can identify threats based on patterns or signatures and stop those emails from being delivered to your users.
However, BEC attacks don’t involve any malware or harmful content being sent. These emails come from legitimate domains and will appear to most email security technologies to be completely innocuous. This means that the email has a high chance of being delivered to your users’ inboxes.
Because they target the human factor within the organization to succeed, once in the email inbox BEC attacks have a good chance at tricking employees into believing they are real. As we’ve covered, BEC attacks often target company executives, like CEOs or CFOs, or employees that work within company finances. When an invoice arrives from an employee like this, people usually trust that it is legitimate, and may go ahead and make the payment without caching the legitimacy of the email.
In addition, attackers are spending more time to develop BEC, spending more time investigating which individuals within an organization are likely to have authority in asking for invoices to be paid.
Considering these factors, it’s no surprise that Business Email Compromise is growing more common and becoming more harmful to organizations. There have been numerous examples of high profile BEC attacks, against organizations of all sizes.
The US Treasury found that the number of business email compromise attacks reported nearly doubled from 2016 to 2018, with nearly 1100 attacks reported every single month. The costs associated also continue to grow, now costing US companies an average of $301 million every single month, according to a Treasury Department Analysis.
When choosing a BEC solution, it’s important to make the right choice for your organization. As no two organizations are identical, it’s important that you take the time to find a solution that matches your needs and addresses your vulnerabilities.
Selecting a solution that doesn’t fit your organization’s profile could leave you with a false sense of security. For instance, your business may release a large quantity of emails and other communications; this could make your brand susceptible to spoofing. Alternatively, you may have a large, disparate work force, the sheer number of employees makes you susceptible to phishing attempts. When selecting a BEC solution, you should consider for the following areas with regard to your own organization:
What Are Your Vulnerabilities?
If you are looking for a solution that can respond to email based threats, it may not be suited to cover SMS or Vishing attacks.
Before deciding what solution is best, look at where you are weakest.
Automation And Configuration
The ability to automate and configure your solution can affect how useful it is to your organization. It may be that you want a solution that you can let run in the background, without any need for input. Equally, you may want a more hands on solution that puts you in control of configuration and management. This decision will be based on your weaknesses, as well as your organizational resource.
What Are Its Features?
When choosing a BEC solution it’s critical to compare the features of each solution to ensure it will work in your environment. URL rewriting, always on connectivity, and database cross-checking gives you the best chance of remediating threats.
As indicated in the previous section, ensuring that your platform has the right features to address the issues that you face is imperative. This can be an overwhelming and confusing area to navigate. Nevertheless, it is one of the most important decisions you face in securing your organization from cyber threats.
