San Jose, CA – June 19, 2025 — A hard truth about today’s threat landscape is that regardless of which top-tier firewall vendor an organization relies on, every perimeter technology will eventually face a vulnerability — whether through a newly discovered zero-day, a misconfiguration, or a third-party compromise. Prudent security planning accepts this reality: it’s not about if an attack will happen, but about ensuring that when a weakness is exploited, robust privileged access controls and precise command restrictions are in place to contain the incident and protect critical operations. Over the past 18 months, every leading enterprise firewall has faced zero-day exploits, targeted intrusions, and critical vulnerabilities actively exploited in the wild. This stark reality proves that no perimeter defense is infallible.
While both attackers and defenders now harness AI to outpace each other, one fact remains unchanged: the real damage happens inside the perimeter, after an initial breach. Without strong controls over privileged access and command execution in the trusted zone, even the most advanced firewalls and detection tools can only slow an attacker down.
This is where TACACS.net stands apart — the proven, dependable solution security teams trust to enforce privileged access and command control inside the perimeter, ensuring attackers hit a barrier where it matters most.
Lessons from Real-World Breaches
Recent high-profile incidents highlight this critical gap:
A major financial services provider spent $27 million recovering from ransomware that exposed more than 16 million customer records.
A global energy consultancy lost 1.5 terabytes of sensitive operational data due to inadequate internal command controls.
A flawed cloud security update triggered a $1 billion global outage, grounding a major airline and freezing financial transactions worldwide.
Nation-state actors breached unclassified government communications through telecom providers, demonstrating that perimeter defenses alone are insufficient against targeted threats.
A major brokerage’s clearing systems were crippled by ransomware, disrupting financial markets and undermining public trust.
In each case, TACACS.net’s advanced privileged access controls could have blocked unauthorized commands, contained lateral movement, and provided real-time audit visibility — limiting damage, costs, and reputational fallout.
