At Darkgate, as operators of an international recruitment agency deeply embedded in the IT and cybersecurity sector, we’ve watched vendors grow from small engineering-driven startups to billion-dollar public companies. When we began, most of the big names were already on the map—Cisco, Palo Alto Networks, Fortinet. Yet over the past decade, a new generation of vendors has rewritten the rules of how fast technology companies can scale, finance, and redefine entire markets. As recruiters, we’re fascinated by the question: how do these companies evolve over time? What defines the early two-year grind of invention, the five-year climb to credibility, and the ten-year march toward market dominance or IPO? And more importantly what separates those who make it from those who fade away?
One of the clearest modern examples is Wiz, founded in 2020 by former Microsoft engineers. In less than five years, the company turned a simple insight—that cloud infrastructure needs continuous, contextualized visibility—into one of the fastest-growing security platforms in the world. No hardware, no appliance business, no box to ship. Just a clean, API-driven architecture that let customers visualize risk in minutes instead of months. The result: valuations once reserved for legacy giants, achieved in record time. Another is SentinelOne, founded in 2013 and public by 2021. It began as an endpoint protection engine competing against established players, but its founders understood early that automation and artificial intelligence would become the center of enterprise defense. The product matured, the team professionalized, and the go-to-market engine scaled. But what really changed the trajectory was timing the global appetite for autonomous security solutions met a perfectly positioned company.
This evolution is more than a financial journey. In the network and security sector, vendors are born from engineering, grow through trust, and survive through integration. The first phase is chaos and velocity demo-driven growth, manual deployments, and hands-on founders. Then comes the professional phase: SLAs, certifications, compliance, channel partnerships, repeatable onboarding. Security is a confidence business. No CIO bets on a vendor that might disappear next quarter. That’s why early vendors build scale optics before they truly have scale partner portals, tier systems, even mock enterprise frameworks to project maturity. But success changes the problem set. Once growth becomes predictable, so do investor expectations. Scaling from 20 to 200 employees is often harder than going from 0 to 10. The challenge shifts from code to culture. Mature vendors like CrowdStrike and Zscaler mastered this balance—they industrialized their operations without killing their engineering DNA. Code still defines their brand, even as revenue and forecasting dictate the rhythm.
Around Series C or D, vendors face their first identity crisis: build for sustainability or chase the next valuation? Many of the 2015–2020 cohort hit this exact wall. The “Next-Gen Security” narrative isn’t enough anymore. Investors want economics, not adjectives. Companies like Snyk, Cybereason, and Armis are navigating that space—strong technology, credible leadership, but under heavier scrutiny. Meanwhile, the old guard is still evolving. Palo Alto Networks, once a pure-play firewall vendor, is now a platform ecosystem spanning SASE, AI-driven analytics, and cloud-native protection. Fortinet did the same, turning its hardware roots into a software subscription empire. The lifecycle doesn’t end with the IPO it restarts there. What’s striking is how compressed time has become. Ten years used to be the benchmark for maturity. Today, a vendor can move from prototype to global player in half that time. Cloud infrastructure, API standardization, and global remote work have shrunk the distance between product and market. Yet the underlying rhythm remains the same: curiosity, control, consolidation.
Many founders confess that the middle phase is the hardest—the years when creativity collides with compliance. Meetings replace coding, quarterly targets replace experimentation. Yet that’s the point where a company either professionalizes or burns out. Cisco, Juniper, Fortinet—they all passed through it. Wiz and Vectra are there right now. Success in this space isn’t about building the most advanced product it’s about building trust fast enough to outlive your first innovation. Modern vendors are no longer box sellers; they are service ecosystems with a product at the core. Their edge isn’t just code it’s credibility.
Whether Wiz eventually goes public or another contender from Europe claims the next major IPO remains to be seen. But the trajectory is clear: from idea to architecture, from platform to public. The real test isn’t valuation- it’s longevity. Because in cybersecurity, technology may change fast, but reputation is the only currency that compounds over time.
