While you scroll through Instagram on a foreign network, a quiet battle is happening in the signaling core—fraud attacks, data breaches, and interconnect exploits. Cellusys is the invisible firewall stopping them. This isn't just software; it's the immune system for the global mobile infrastructure.

"In the shadow economy of SS7 and Diameter attacks, Cellusys doesn't just build walls—it builds the intelligence to see the attack before it happens."

Their digital footprint reveals a company that's mastered the art of being essential yet invisible. With only 4,034 monthly visits, they don't need massive traffic because each visitor is likely a network architect or CTO from a Tier-1 carrier. The fact that 41% of traffic is direct—not from ads or SEO—proves their brand is etched into the minds of telecom professionals who type 'cellusys.com' directly when they need to solve a signaling crisis.

• Specialized dominance in SS7/Diameter firewalls—avoiding the commodity cybersecurity trap
• Ultra-efficient model: $325K revenue per employee, suggesting high-margin, low-churn enterprise contracts
• Strategic content marketing targeting precise technical pain points (tcap, fasg, diameter)
• Social presence focused on LinkedIn and Twitter—where telecom decision-makers actually live
