Evidence

Every verdict shows its work

"The filter blocked it" is not an answer you can give an auditor, a regulator, or the executive whose message got quarantined. A gateway hands you a rule number. Three things follow from that, and security teams live with all three.

01

You file a ticket instead of making a fix

When the filter is wrong, there is nothing legible to open and correct. You log a case with the vendor and wait. The mail your business needs stays held while you wait, and the same message can be held again next week.

02

The pressure only runs one way

A blocked invoice produces a complaint within the hour. A missed phish produces nothing at all, until it becomes an incident months later. So the quiet, rational response to a filter nobody can inspect is to loosen it. That decision is invisible too, and it is how opaque tooling ends up making an organization less safe.

03

A rule number is not an audit trail

A policy ID does not tell a regulator what was examined. It does not tell your CFO why their message was held for six hours. And it does not tell the analyst who inherits the queue next quarter what the last one was thinking.

Aegis writes down what it saw, which agent saw it, and why it mattered, for every message it judges. Not a score, and not a rule number. A record you can read, argue with, and hand to someone else.

Reviewable

Open any verdict and read the full agent trail: the signals, the conclusion, the timestamp, and the agent that produced each finding.

Exportable

Verdicts, indicators, and audit events push into your SIEM and case management. The evidence lives where your team already works.

Reversible

Release a message and Aegis records who released it and why. Your quarantine decisions become a documented trail rather than a black box.

Measured

In a fifteen-day head-to-head on live customer mail, the incumbent tool held a legitimate customer invoice, a vendor security report, and an internal production-deploy approval. Aegis raised no false positives on the same mail over the same window. All three of those messages were unusual. None of them was an attack.

What changed after
they connected

Security leaders at LangChain, Mesh and Lokker on what the agents caught, what stopped needing tuning, and what they no longer have to explain to anyone.
What impressed us about Aegis AI is that their agents actually adapt in real time. No rule-writing, no tuning, no chasing false positives. We deployed in minutes and saw threats we'd been missing effortlessly with the agent's reasoning for each email, no black box. It's security that finally keeps pace with the attackers.
Arthur Stromquist
Security Lead, LangChain
Aegis is the first solution that truly changes the game. They came into Mesh and stopped attackers in their tracks. Our dashboard shows everything from fuzzing attempts to AI-generated spear phishing and BEC, and Aegis catches them all, without my team wasting time managing rules.
Bam Azizi
CEO, Mesh
 I was thrilled at how quick the installation process was. Usually with these tools there is a lot of configuration of things like suppression lists. With Aegis it just worked. We immediately saw threats to our accounting, engineering, and executives teams in the dashboard. Aegis enabled us to see and stop these threats without our team manually hunting them down.
Ian Cohen
CEO, Lokker
The mark of a great email security system is that we don't have to manage it. Aegis was able to come in and help us stop attacks without requiring our team to spend extra time on it. It's put a stop to the increasing number of attacks - even those using compromised infrastructure and AI to customize attacks to specific employees.
Arjun Mukherjee
CTO, Mesh
AegisAI was incredibly easy to install. With Aegis we just don't think about phishing anymore.
Sanjay Mahalingam
Founder, Spacetil
What impressed us most about Aegis AI isn’t just the technology, it’s the team behind it. Coming from years of building Google’s core security infrastructure, they’ve brought that same expertise to tackling modern email threats. The result is a solution that stops sophisticated phishing and BEC attacks without slowing our business down.

Security review

Answered before your reviewers ask

The hard part of buying security software is not the demo. It is the questionnaire, the DPA, and the architecture review. Here is what your security, privacy, and procurement teams will want in writing.

Deployment model
API integration with Microsoft 365 and Google Workspace. No MX record change, no gateway in the mail path, no endpoint agent.
Certification
SOC 2 Type II.
Data protection
Encrypted in transit and at rest. Aegis does not retain full message content beyond what analysis requires.
AI and your data
Analysis runs inside the Aegis boundary. Your mail is not shared with third-party AI labs and is not used to train their models.
Failure mode
Aegis sits beside mail flow rather than inside it. If Aegis is unavailable, mail continues to deliver normally.
Response window
Agents reach a verdict in seconds and act post-delivery, pulling a malicious message back before users see or click it.
Rollback
Revoke the OAuth grant. Access ends immediately and there is no mail-flow change to unwind.
Who built it
Founded by the team that ran phishing and malware defense at Google scale across Safe Browsing, reCAPTCHA, and Web Risk.
FAQ

SEG Migration FAQs

Answers to common questions about how Aegis can enhance your team's inbound email security.
  • How is Aegis AI different from traditional Secure Email Gateways (SEGs)?

    Unlike secure email gateways that rely on static rules, signatures, or domain reputation, Aegis AI continuously adapts to new attack patterns and threat actors. Our AI agents evaluate sender behavior, language intent, and hundreds of other signals stopping sophisticated attacks like no-payload phishing and Adversary-in-the-Middle (AiTM) before users see or click.

  • How does Aegis handle zero-day email attacks?

    Traditional solutions fail against brand-new email security threats. Aegis AI’s agents use real-time analysis, natural language understanding, and behavior signals to identify BEC and phishing emails the moment they appear, before they’re added to threat intelligence feeds.

  • Can Aegis AI reduce the workload on my security team?

    Yes. By stopping advanced email threats before users see or click, and providing automated triage for suspicious messages, Aegis AI significantly reduces alert fatigue, freeing your team to focus on strategic initiatives.

    • Why should I choose Aegis AI over other inbound email security tools?

      Our platform combines deep expertise from >20 years combined building security products (reCAPTCHA, Safe Browsing, Web Risk and more) with cutting-edge AI to deliver unmatched protection, lower false positives, and effortless integration, ensuring your business stays secure without slowing operations.

    • How easy is it to deploy Aegis AI?

      Deployment is API-based, requiring no hardware, no MX changes, no network changes and no complex policies. Most teams connect in about two minutes and work from a single dashboard for insights and automated response. Nothing sits in the mail path, so there is no migration to plan and nothing to unwind if you disconnect.
      Aegis AI does not score how unusual a message looks. A panel of agents reads what the message is actually asking for, checks that claim against the sender's history and the surrounding context, and records the reasoning. That is what catches an attack with no prior signal, because it does not depend on having seen one like it before.

      In contrast, traditional methods may miss these novel attacks since they depend heavily on existing databases of threats. Additionally, AI can continuously learn from new data, improving its accuracy over time, while traditional methods typically require manual updates to adjust to new phishing tactics.

    • How does AI-powered email protection differ from traditional tools?

      Email protection based on artificial intelligence leverages advanced algorithms and machine learning to detect and respond to email threats in real time, whereas traditional email security solutions often rely on predefined rules, filters, or signatures to identify known threats.

      Aegis AI's agents reason about what a message is asking for and verify whether the claim holds up, then attach that reasoning to the verdict. A targeted attack written for one company has no prior signal anywhere, so reasoning is what catches it.

      In contrast, traditional methods may miss these novel attacks since they depend heavily on existing databases of threats. Additionally, AI can continuously learn from new data, improving its accuracy over time, while traditional methods typically require manual updates to adjust to new email threats.
      Aegis AI reads the request itself: who is asking, what they want changed, and whether the thread and the sender's history support it. A payment-detail change from a compromised but otherwise legitimate vendor account passes every authentication check, which is exactly why signature and reputation filters miss it.

      In contrast, traditional methods may miss these novel attacks since they depend heavily on existing databases of threats. Additionally, AI can continuously learn from new data, improving its accuracy over time, while traditional methods typically require manual updates to adjust to new email threats.
