There was a time when cybersecurity teams operated under the assumption of a “grace period.” When a new Common Vulnerabilities and Exposures (CVE) record was published, defenders typically calculated a window of 30, 60, or even 90 days to test, schedule, and deploy patches across their enterprise infrastructure.
That grace period no longer exists. And for good reasons.
Industry threat research from Mandiant, Rapid7, and the CISA Known Exploited Vulnerabilities (KEV) catalog paints a stark reality: over the past decade, the average Time-to-Exploit (TTE)—the duration between a vulnerability being publicly disclosed and its active weaponization in the wild—has completely collapsed.
In 2016, organizations had an average of 84 days before threat actors weaponized a vulnerability. By 2024, that window had shrunk to just 5 days.
Today, we have entered the era of the Inverted Window. Driven by AI-driven threats, automated vulnerability scanning, and commercialized Initial Access Brokers (IABs), threat actors routinely identify and exploit unpatched vulnerabilities days before a public patch or advisory is even released. That’s why organizations including the Federal Government (through CISA’s Binding Operational Directive 26-04) are requiring exploits in CISA’s KEV to be patched within 3 days. But the reality is we are now in a world where patches must be applied as soon as possible because minutes count.
For IT systems, fast-turnaround automated patching has become standard practice. But in the world of Operational Technology (OT) and Enterprise IoT—where tens of thousands of smart cameras, access control systems, HVAC controllers, and building sensors live—organizations are falling dangerously behind.
Threat actors know that enterprise OT/IoT devices are the soft underbelly of modern network perimeters. These unmanaged endpoint devices are frequently deployed with default or rarely rotated passwords, lack 802.1x network certificates, and run on firmware that hasn’t been updated in years. If your remediation workflow relies on manual processes, you are attempting to fight microsecond automated attacks with manual, analog speed.
Organizations (Falsely) Fear The Costs and Staffing of OT Remediation
Why do so many security and facilities teams hesitate to update OT/IoT firmware or rotate credentials rapidly? The answer almost always comes down to operational cost and resource constraints.
Traditional, manual OT/IoT patching is agonizingly slow and expensive. Manually updating a single IP camera or building management gateway requires a technician to locate the device, access its individual management console, verify firmware compatibility, update credentials, and test connectivity. Industry metrics show that the average labor cost to manually apply a single patch or rotate a credential on an OT/IoT device ranges between $10 and $20 per device. For an enterprise managing 10,000 physical security cameras, access control panels, and smart HVAC controllers, a single enterprise-wide patch cycle costs between $100,000 and $200,000 in manual labor alone—not to mention hundreds of hours of team bandwidth.
The Viakoo Advantage: $0.14 Per Device
The most important issue is speed; threats must be remediated ASAP. Only automation can get there. Organizational risk reduction is the highest form of return on investment in an automated remediation solution.
Automation also entirely changes the economics of performing cybersecurity. With the Viakoo Action Platform, updating firmware, rotating non-compliant passwords, and provisioning 802.1x/TLS certificates is transformed from a multi-week manual chore into a centralized, push-button operation.
Instead of spending $10 to $20 per endpoint, remediating an OT/IoT device using Viakoo costs approximately $0.14 per device, plus or minus a few cents.
By slashing remediation costs by over 98%, Viakoo enables security teams to patch immediately upon CVE release, enforce continuous zero-trust password policies, and maintain audit-ready compliance without blowing past operational budgets.
Don’t Let a 3-Day Exploit Window Become a Corporate Breach
The data is clear: waiting weeks to patch OT/IoT infrastructure is no longer a viable security strategy. When exploit weaponization takes place in days or hours, automation is the only defense that scales.
By replacing slow, $15 manual updates with $0.14 autonomous remediation, Viakoo empowers organizations to shrink their attack surface, prove continuous compliance, and lock down OT/IoT devices before attackers ever get the chance to exploit them.
