We kept seeing the same breach. Different companies. Same gap.
A dependency that scanned clean. A runtime behaviour nobody was watching. An incident that shouldn't have happened and tools that couldn't have prevented it.

Security tools are solving the wrong problem.
Security tools are solving the wrong problem.
The security industry has spent twenty years getting better at reading source code. SAST tools, SCA tools, vulnerability scanners. They're sophisticated, well-funded, and increasingly accurate at what they do.
But attackers don't exploit source code. They exploit what it does at runtime. That gap, between what code says and what it does, is where modern attacks live. Supply chain compromises. Malicious dependencies. Packages that scan clean and behave badly. Every major supply chain incident of the last five years has exploited this gap. And almost no security tooling was watching for it.

We built Ossprey to watch that gap. Continuously. Automatically. Without getting in the way of the teams who are actually building things. We built Ossprey to bring a sense of calm.

Real risk only
We don't surface theoretical vulnerabilities. We don't flag what might be exploited. If Ossprey raises something, it's because an attacker could use it, validated against real runtime behaviour. We'd rather miss a low-probability edge case than train your team to ignore alerts.

Invisible until it matters
Security tooling that slows teams down gets worked around. We've seen it happen. Ossprey is designed to have zero presence in your workflow until it finds something, then it's exactly where you need it to be.

Built for how teams actually work
Most security tools were designed for enterprises with dedicated security teams. We built Ossprey for the CTO who is also the CISO, the engineering lead who owns security by default, and the startup that's moving fast and can't slow down to do it.

Ossprey was founded by engineers who've worked across application security, open source infrastructure, and developer tooling. Who got tired of recommending tools they didn't trust to catch the things that actually mattered.

Ossprey's core engine is open source, because we think security tooling you can't inspect is security tooling you can't trust. The community has shaped how Ossprey detects behaviour, what it flags, and what it ignores. That will continue.

If you've seen a supply chain attack pattern that tools aren't catching, we want to hear about it.

Keep it simple
What's the most important thing right now?
What's its simplest solution?
What's the simplest description?
Complexity kills startups. As we grow, we protect speed and quality by keeping our product, processes, and communication as simple and clear as we can, while remaining secure, reliable, and easy to adopt.
Do the right thing
Be respectful and compassionate
Take accountability
Speak up
Work with compassion, fairness, and integrity even when it's inconvenient. We act like adults: direct, honest, accountable, and respectful. Security companies live or die on trust - we are honest about what we know, what we don't.
Solve Problems
Solve the root cause, not symptoms
Provide real value
Work hard to do this
We win by focusing relentlessly on real customer problems and validating that we're solving them. We prioritize outcomes over activity, and we take outcomes seriously. We aim for consistently high performance - quality matters, even when moving fast.
Win together
How do we set each other up to succeed?
Are we creating lift or drag for the team?
Have we shared context, not just tasks?
We succeed as a team or not at all. We share context early, give each other ownership, and level each other up. Great teams are built on trust, transparency, and shared accountability. We invest in each other's growth and help each other perform at our best.
Clarity
What's the most important thing right now?
What's its simplest solution?
What's the simplest description?
Ambiguity creates risk - in security products and in teams. We communicate with precision and transparency, internally and externally. We make expectations, decisions, priorities, and uncertainties explicit so everyone can act with confidence.
