Israeli cybersecurity startup Oligo Security has raised $60 million in a Series B funding round, the company announced this week, as enterprise demand for runtime application protection continues to accelerate. The round brings the Tel Aviv-based firm’s total capital raised to approximately $90 million, underlining investor confidence in a segment of the security market that has grown sharply alongside the proliferation of cloud-native software architectures. The raise was reported by Globes, the Israeli business publication.

Oligo operates in the runtime security space, specifically targeting vulnerabilities that exist within open-source libraries and dependencies at the moment an application is actually executing — a layer of the software stack that traditional static analysis tools struggle to protect. As organisations increasingly rely on open-source components to accelerate software development, the attack surface embedded in those dependencies has expanded considerably, creating both a commercial opportunity and a significant enterprise risk. The company’s approach is also relevant to broader Israel tech sector momentum, which has continued attracting international venture capital despite regional uncertainty.

What Oligo Does and Why It Matters

The core of Oligo’s technology is an eBPF-based observability agent that runs inside live production environments and monitors application behaviour in real time. Unlike perimeter-based security tools or static code scanners, Oligo’s platform identifies whether a known vulnerability in a library is actually reachable and exploitable during runtime — a critical distinction that allows security teams to prioritise remediation efforts rather than chase theoretical risks flagged by dependency scanners. Industry estimates suggest that the vast majority of flagged open-source vulnerabilities in any given enterprise codebase are never actually triggered in production, making runtime context a significant efficiency lever for security operations teams.

The company counts a number of large enterprises among its customers and says its platform integrates across major cloud environments including AWS, Google Cloud, and Microsoft Azure. Oligo also targets the application security posture management market, an emerging category that analysts have projected will grow substantially over the next five years as chief information security officers seek consolidated visibility across increasingly complex cloud workloads. The company competes in a competitive but high-growth segment that includes players such as Contrast Security and Datadog’s application security suite, though Oligo’s specific emphasis on open-source library risk at runtime represents a differentiated positioning.

Investor Backing and Expansion Plans

The Series B was led by Greenfield Partners, with participation from existing investors including Lightspeed Venture Partners and ballistic Ventures. The involvement of repeat investors signals continued conviction in the company’s trajectory since its Series A. Oligo was founded in 2022 by Gal Elbaz, Avshalom Hilu, and Nadav Czerninski, all of whom bring backgrounds from Israeli intelligence and enterprise software development — a founding profile common among the country’s most technically credentialed cybersecurity ventures.

The company has indicated it intends to deploy the new capital primarily toward expanding its go-to-market presence in North America and Europe, where enterprise security budgets remain comparatively robust despite broader technology spending pressure. Engineering headcount growth, particularly in research and development focused on extending runtime visibility to AI-generated code and large language model supply chains, is also cited as a priority. The latter is a nascent but fast-emerging risk category: as developers increasingly rely on AI coding assistants to generate software components, the provenance and security of AI-produced dependencies has become a growing concern among enterprise security architects.

The raise also reflects a wider recovery in cybersecurity venture activity after a period of valuation compression across the technology sector. Investors appear increasingly willing to back companies addressing structural, long-cycle problems in enterprise security rather than point solutions, and Oligo’s positioning at the intersection of open-source dependency risk and cloud-native runtime behaviour places it in a category that shows few signs of diminishing relevance. Whether the company can translate its technical differentiation into durable enterprise contracts at scale will ultimately determine the return profile of this latest capital injection.
