We’re the most committed cybersecurity partner for cloud-native SMBs
In a space crowded with Fortune 500 security consultants and dashboards, we stand out by offering what’s most often missing: managed full-cycle security for SMBs.
Help fast-growing businesses scale with confidence.
We treat security as a business growth enabler. With over a decade of experience supporting pre-enterprise teams, we understand their growing pains — and we know how to guide them to what’s next.
The go-to security team for pre-enterprise companies
Most cybersecurity firms either target massive enterprises or offer one-size-fits-all solutions. We built Protagonist specifically for the in-between — fast-scaling companies that have outgrown basic security but aren’t ready for enterprise-grade complexity.
Full security lifecycle coverage
From compliance readiness to managed detection & response.
Embedded developer mindset
Developer-friendly security that doesn’t block product delivery
Hands-on partnership
We implement and evolve your security alongside your business.
Designed for SMBs
We’re built for pre-enterprise. No enterprise bloat, no startup shortcuts.
We’re a cybersecurity practice built on the foundation of a 500+ person tech consulting firm with a decade of experience and 200+ successful projects for startups and Fortune 500s alike.

What drives us
We’re security partners who believe that great security should accelerate your business, not slow it down.
Ownership over reports
Most security firms deliver reports and walk away. We roll up our sleeves and fix what’s broken. When we find a vulnerability, we help you patch it. When we identify a gap, we help you fill it. Your security outcomes become our responsibility, not just our recommendations.
Security as strategy
We treat security as your competitive advantage. Every control we implement, every process we design, and every audit we prepare is focused on one goal: helping you win more deals, attract better talent, and scale faster. Security isn’t just about checking boxes — it’s about opening doors.
Built for builders
We speak your language because we understand your world. CI/CD pipelines, containerized deployments, infrastructure as code — we’ve been there. Our security implementations integrate with your development workflow because we design them with developers.
