TESTIMONIALS

Trusted by Teams
Who Defend at Scale

From high-growth startups to Enterprise customers, AegisAI helps security teams move faster, detect more advanced threats, and reduce noise for busy security teams.

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.

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 they reach inboxes.

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 blocking advanced email threats pre-delivery 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, MX changes, network changes, or complex policies. Admins can set up the platform in under 30 minutes and leverage a simple dashboard for insights and automated response workflows. This makes it ideal for either teams wanting to spend time on critical projects vs alerts or smaller businesses who can’t rely on a dedicated team to run their security.
Aegis AI can analyze patterns and behaviors in emails, recognizing anomalies that might suggest a phishing attempt even if it's a new or sophisticated attack that hasn't been seen before. This proactive approach allows for a more dynamic defense against evolving threats.

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 can analyze patterns and behaviors in emails, recognizing anomalies that might suggest a threat even if it's a new or sophisticated attack that hasn't been seen before. This approach allows for a more proactive and dynamic defense against evolving threats and advanced social engineering tactics.
