There’s been a major surge of capital into the cybersecurity space, and it’s happening right in step with the RSA Conference 2025 in San Francisco.

More than 30 cybersecurity companies collectively raised over $1.7 billion in April alone. It’s one of the strongest signals yet that investors are still heavily backing cyber defense, even as other sectors slow under economic pressure.

What’s standing out this year is the dominance of Artificial Intelligence. At RSAC 2025, AI is more than a trend—it’s the engine behind the next phase of cybersecurity innovation.

Companies are integrating AI into everything from threat detection and incident response to vulnerability management and automated security workflows. There’s also serious attention being paid to AI-related risks, especially around how enterprises deploy generative models and cloud-based services.

Funding momentum hasn’t slowed, even as venture capital tightens elsewhere. The need for reliable, scalable cybersecurity tools continues to grow, and investors clearly see this space as both resilient and future-proof.

Two major players led the way in April’s funding rounds:

• ReliaQuest raised $500 million to expand its threat detection and security operations platform.
• Chainguard brought in $356 million to grow its developer-centric tools focused on software supply chain security.

Together, these two companies made up more than half of the total funding raised across the sector last month.

At the same time, JPMorgan Chase CISO Pat Opet published a direct message to SaaS providers, calling out what he sees as a critical weakness in today’s cloud models. His open letter warns that “convenience can no longer outpace control”—a reference to the widespread use of OAuth-based architectures that, in his view, introduce system-wide single points of failure.

Opet didn’t hold back. He pointed to a culture of rushed product releases, often without default security enabled, that has effectively eroded long-standing security boundaries. He raised particular concern about hyperscale providers whose security gaps could ripple into global banking systems if exploited.

His message landed in the middle of a funding-heavy, innovation-packed week—adding weight to the idea that while the cybersecurity sector is growing fast, security fundamentals can’t be an afterthought. The tension between speed and control is clearly top of mind for both CISOs and investors right now.
