About Felk
We exist so your team doesn't have to become security experts.
Most SaaS companies reach a point where security can no longer be an afterthought — but hiring a full security team isn't practical, and stitching together a collection of tools doesn't add up to real protection. Felk was built to solve exactly that problem.
We combine AI-powered security products with hands-on human expertise — working as an extension of your team to protect your entire infrastructure, navigate compliance, and give you the security posture your customers and investors expect. Without the overhead of building it yourself.
Felk is a Cybersecurity as a Service (CSaaS) provider helping growing SaaS companies stay secure, compliant, and enterprise-ready.
Why we exist
The problem most SaaS companies don't see coming
Security tends to become urgent at exactly the wrong moment — when you're preparing for a big enterprise deal, approaching a compliance audit, or responding to an incident that's already underway. By that point, the gaps in your security posture are already costing you.
The tools most companies rely on were built for a different era — point-in-time products that protect one layer, generate alerts no one has time to review, and require specialist expertise to configure and maintain. Stitching them together doesn't create a security function. It creates noise.
And hiring your way out of the problem is harder than it sounds. Experienced security professionals are expensive, scarce, and rarely needed full-time at the growth stage — but the risk they're there to manage is constant.
Security shouldn't be the reason you lose your first enterprise deal — or your customers' trust.
Felk exists to change that equation. We act as your dedicated security function — bringing AI-powered tools and experienced human consultants together under one managed service. You get the coverage, the expertise, and the documentation your business needs, without building a team from scratch or managing a collection of disconnected products.
How we work
AI tools and human expertise — working together
A lot of security vendors sell you a dashboard and leave you to figure out the rest. Felk works differently. We combine intelligent technology with experienced people — so that what the AI surfaces, our team acts on.
- 01.We become an extension of your team
Felk isn't a product you buy and configure yourself. We work alongside your engineering and operations teams — or in place of a security function you don't have — handling the day-to-day management, monitoring, and response that keeps your business protected.
- 02.AI that covers your whole infrastructure
Our AI-powered platform monitors across web applications, email, identity, and endpoints — learning continuously and detecting novel threats in real time. No manual rule updates. No gaps between your tools. One unified view of your security posture.
- 03.Humans who interpret, decide, and act
Our security consultants don't just hand you alerts. They interpret what the AI surfaces, respond to incidents, guide your compliance journey, and make decisions that require context and judgement — not just pattern matching.
- 04.Simple to start, powerful over time
Felk integrates with your existing infrastructure and also provides purpose-built products for specific security challenges. Deployment requires no code changes and takes minutes. Protection improves continuously as our AI learns your environment.
- 05.Managed means accountable
We don't walk away once you're set up. Felk's team actively monitors your security, responds to incidents, maintains your compliance documentation, and keeps your protection current. If something goes wrong, we're already on it.
What we believe
The convictions we build from
- People and technology, together
- AI can detect faster than any human. But humans understand context, make judgement calls, and take responsibility in ways no model can. Felk is built on the belief that the best security combines both — and that neither alone is enough.
- Simple should win
- Security is genuinely hard. The tools that sit in front of it shouldn't be. Everything Felk builds is designed to be clear, deployable quickly, and manageable without a specialist degree.
- Security should enable growth, not block it
- Too often, security becomes a bottleneck — something that slows deals, delays launches, and drains engineering time. We believe it should be the opposite: the thing that lets you move faster, enter new markets, and win enterprise customers with confidence.
- Managed means we're accountable
- When we say fully managed, we mean it. Felk doesn't hand you tools and walk away. We stay involved, stay responsible, and treat your security as something we own — not something we've sold you.
- Built for where threats are heading
- We're not looking backwards. Felk is built for the era of AI-assisted attacks and autonomous threats — and we stay ahead of that curve so you don't have to think about it.
Leadership
Meet the founder
Uditha Atukorala
Founder & CEO
Uditha Atukorala (Udi) is the Founder and CEO of Felk, and the driving force behind its conviction that great security should be simple, intelligent, and human.
A technologist at heart, Uditha has spent over a decade as a CTO — leading and scaling cross-functional engineering teams across multiple startups, and building the kind of massively scalable software platforms that underpin fast-growing products. He brings the same hands-on rigour to Felk: writing and reviewing code, designing systems from first principles, and maintaining an attention to detail that shows in everything the product does.
Uditha is also a committed open source contributor — author of gRPCxx, the fastest gRPC server implementation, and Ruek, a global-scale authorisation system. Both reflect his belief that the best infrastructure is fast, simple, and well-crafted.
He founded Felk to take on a problem he saw first-hand: that the security tools available to growing businesses were outdated, fragmented, and increasingly inadequate for the threats they face today. Felk is his answer — a full-service cybersecurity function that combines AI-powered protection with experienced human expertise, built with the precision and craft he's applied throughout his career.
Uditha is backed by a team of security experts and engineers, who share his conviction: that every growing SaaS company deserves the kind of security that used to be reserved for enterprises with the budget to match.
