AegisAI Secures $36 Million to Combat AI-Driven Phishing Attacks

Washington DC, United States Jul 24, 2026 ALN: Hackers are increasingly using AI to launch attacks on a massive scale, with email emerging as a primary target. AI can quickly aggregate personal information—such as information about coworkers, active projects, and recent travel itineraries—allowing bad actors to instantly craft convincing messages that look authentic.

Last year, former Google security executives Cy Khormaee and Ryan Luo, who previously worked on developing safe browsing technology and reCAPTCHA, teamed up to launch AegisAI, a startup that uses AI agents to stomp out these threats, known as spear phishing.

With a decade of experience preventing email hacks, the AegisAI co-founders realized that existing rule-based systems for preventing hacks—relying on “if-then” logic—are too slow and limited to catching AI-crafted malicious emails. So they developed AI agents that quickly analyze each message as a human would, paying attention to small anomalies that even the most elaborate checklist wouldn’t catch.

Less than a year after its launch, AegisAI says its tech has been adopted by dozens of customers, including crypto payments company Mash, AI startup LangChain, and Google-owned privacy compliance platform Lokker. That demand has just helped AegisAI raise a $36 million Series A led by Battery Ventures, with participation from existing backers Accel and Foundation Capital. The fresh funding brings the startup’s total capital to $49 million.

“AI-powered attacks bypass existing controls more than half the time now, which means they’re almost twice as effective as they used to be,” Khormaee told . “They’ve researched you, they understand everything about you, and they’re targeting attacks that are perfectly bespoke to you.”

Khormaee claims that AegisAI’s agents can spot threats traditional email security systems may miss entirely. For instance, the startup’s AI can catch malicious PDF attachments that look legitimate at first, including ones with built-in passwords and CAPTCHAs, which are often used to fool standard spam filters.

When Dharmesh Thakker, general partner at Battery Ventures, noticed an increase in email attacks, he set out to invest in a startup that could defend against AI with AI, one aiming to replace legacy email security tools with agentic-driven defense.

“The bad guys are using email to attack us using AI at a much faster pace than we can keep up with,” Thakker told . “Defending against that is going to be a number one priority for a lot of companies.”

AegisAI isn’t the only startup using AI to analyze the context of every incoming email to detect fraud and impersonation attempts. Lightspeed-backed Ocean is also trying to displace established vendors like Proofpoint and Mimecast, along with newer players like Abnormal Security.

However, given that AegisAI is led by experts who helped secure Gmail, the most popular email system in the world, Thakker believes the startup has the best shot at becoming the leading new hack-prevention company.

While AegisAI is starting with email, the startup has its sights on eventually expanding to other areas of defense, such as data security. “The core idea of building customized, highly advanced agents that can do investigations is going to [determine] who becomes the next dominant security company,” Khormaee said.

The rise of AI-driven phishing attacks represents a significant evolution in the cyber threat landscape. Traditionally, phishing attacks relied on generic messages sent to a broad audience, hoping to trick a small percentage of recipients into divulging sensitive information. However, with the advent of AI, attackers can now create highly personalized messages that are more difficult to detect and block.

AI technologies can analyze vast amounts of data to craft messages that not only mimic the writing style of legitimate correspondents but also incorporate specific details relevant to the recipient. This capability makes AI-driven phishing attacks particularly insidious, as they can exploit trust and familiarity, leading to higher success rates.

The implications of these developments are profound. Organizations are increasingly recognizing the need for advanced security measures that go beyond traditional methods. AegisAI's approach, which leverages AI to understand the context and nuances of email communications, represents a shift towards more proactive and adaptive security solutions.

As businesses continue to digitize their operations and rely on email for communication, the stakes have never been higher. Cybersecurity is not just a technical issue; it has become a critical component of business strategy. Companies are investing heavily in cybersecurity solutions to protect their data, reputation, and customer trust.

The funding secured by AegisAI is indicative of the growing interest in AI-driven cybersecurity solutions. Investors are keen to support startups that demonstrate the potential to revolutionize how organizations defend against cyber threats. The $36 million Series A funding round, led by Battery Ventures, highlights the confidence in AegisAI's technology and the urgency of addressing the escalating threat posed by AI-enhanced attacks.

Moreover, AegisAI's success could influence the broader cybersecurity landscape. As the company develops its technology and expands its offerings, it may set new standards for email security. This could prompt established players in the industry to innovate and enhance their own products to remain competitive.

The competitive landscape for cybersecurity solutions is evolving rapidly. Startups like AegisAI and Ocean are emerging as formidable challengers to traditional security vendors. As these companies develop new technologies to combat AI-driven threats, they are likely to reshape the market dynamics and force established players to adapt.

In conclusion, AegisAI's innovative approach to combating AI-driven phishing attacks is a timely response to a growing threat. The startup's ability to leverage AI to analyze email communications and detect sophisticated attacks positions it as a key player in the cybersecurity space. As organizations continue to grapple with the challenges posed by advanced cyber threats, the demand for effective solutions like those offered by AegisAI is expected to rise, making it a crucial player in the ongoing battle against cybercrime.
