Why I’m Joining Pillar Security by Jenna Raby

For the past 15 years, I had the honor of being on the front lines of cybersecurity’s biggest battles. At RiskIQ, we defined the Threat intelligence and attack surface management category by allowing businesses to see their entire digital footprint through the eyes of an attacker. At Zero Networks, we did it again by pioneering a new category in zero-trust security, making it effortless for companies to stop devastating breaches like ransomware.

Every major technology shift creates a new security frontier. 

And today, no shift is bigger - or more urgent - than AI.

That’s why I’m thrilled to Join Pillar as SVP of Growth. 

The AI Security Blind Spot: It’s Not in the Code, It’s in the Behavior

AI is unlike any other system we’ve had to defend. It is now woven directly into business logic- the workflows, decisions, and operations that define how organizations run. Treating AI as a siloed IT problem or applying traditional AppSec scanners to models fundamentally misses the point. The real risk isn't just in the code; it's in the emergent behavior.

This is where continuous monitoring changes the game. By baselining normal agentic behavior, we can spot “agentic drift” the moment it occurs and automatically correct it before adversaries can exploit it. Relying on reactive security measures is no longer enough ; the opportunity lies in anticipating threats. Security becomes self-healing, where the system predicts what will happen and addresses it before impact.

Because AI is integrated into core operations, securing AI means securing the way a business operates. This requires a holistic and predictive approach that covers the entire lifecycle, continuously.

Why Pillar 

This is where my journey led me to Pillar. I wasn’t looking for a company that simply added a few AI checks to a legacy product. I was looking for the team building a predictive and purpose-built platform for this new reality.

That’s what Pillar technology delivers - a recursive loop of defense that evolves as fast as the systems it protects. This includes:

• Discovery – Full visibility into where and how AI is being built, deployed, and used across the enterprise.
• AI Security Posture Management – A data-driven, threat-intelligence-fed baseline that continuously monitors for risks and misconfigurations.
• Red Teaming & Testing – Actively probing models and systems to surface weaknesses before attackers do.
• Adaptive Runtime Guardrails – Automated defenses that detect drift, correct behavior, and prevent exploitation in real time.
• Monitoring and Governance - Establishing continuous oversight and policy enforcement to ensure AI systems remain aligned with organizational standards and compliance requirements

What excites me most is how these components don’t exist in silos—they feed into one another, creating a self-reinforcing cycle of insight and protection. That’s fundamentally different from point solutions or legacy approaches. It’s an operating system for securing AI at scale.

Beyond the technology, Pillar recognizes that AI is not just an IT problem but an enterprise challenge - so its approach unites People, Process, and Product to drive security at every level:

• People – Empowering security teams with knowledge and best practices for AI security.
  
• Process – Guiding organizations with the SAIL framework to discover, evaluate, and protect their AI/ML systems
  
• Product – Delivering a platform that solves the most critical technical challenges across the AI lifecycle.
  

This combination is unique. Pillar is not only responding to today’s AI security needs - it’s defining the category.

The Time Is Now

The market is already validating this approach. With a recent $9M seed funding round, the launch of the SAIL framework, early adoption by forward-thinking enterprises, and recognition in Gartner research, Pillar isn’t just joining the conversation on AI security—it’s leading it.

I’m inspired by Dor Sarig and Ziv Karliner’s vision, the strength of the R&D and product teams, and the energy of a company that is not merely participating in the AI security market, but setting the standard for it.

I joined Pillar because securing AI is the defining challenge of our generation in cybersecurity. We are at a pivotal moment where we can empower enterprises to innovate boldly and embrace the full potential of AI with confidence. For me, this isn’t just a new role, it’s a mission to help build the trusted foundation for the AI-powered future.

And we’re only getting started.
