OUR MISSION

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.

Enterprise-grade processes, startup-friendly delivery

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.

  • Predictable outcomes

    Thanks to our mature project management practices, you get the security outcomes always on time, without scope creep.

  • Faster time to value

    No figuring it out as we go. Our proven processes mean we can hit the ground running from day one.

  • Professional execution

    With established systems in place, we ensure consistent quality from client onboarding to incident response.

  • Scalable partnership

    As your needs evolve, our established processes can scale to match. We have the operational maturity to grow with you.

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.
