MTTI: The key to IT stability and security

Mean Time to Identify (MTTI) demystified

In IT, the most dangerous threats are often those that go unnoticed. Every second that a problem remains undetected, the potential for damage grows. This critical time window is measured by mean time to identify (MTTI) - the average time it takes a team to detect an incident after it has occurred. It is the first phase of incident response and is calculated as follows:

MTTI = Time of discovery - Time of occurrence of the incident

A high MTTI is more than just a bad metric; it is a direct indicator of business risks such as financial losses, SLA violations, and reputational damage. For security teams, a long attacker dwell time means more damage, as demonstrated by the 2017 Equifax hack, where the threat went undetected for over 70 days. For DevOps teams, a low MTTI means less downtime and happier customers. MTTI does not measure the quality of your system, but rather the effectiveness of your monitoring.

The problem with conventional approaches to MTTI reduction

Traditionally, tools such as SIEM systems, log management and APM solutions are used to reduce MTTI. However, these approaches reach their limits in modern environments. The sheer flood of data leads to an overwhelming number of alerts, many of which are false or irrelevant. This "alert fatigue" causes critical warnings to be overlooked, which ironically increases the MTTI.

The fundamental problem: these tools report symptoms ("service is down") but not the cause. They lack the ability to automatically correlate these symptoms with the triggering event, which is almost always a change in the environment. Teams have to manually establish the connections, which is the main reason for high MTTI.

The Versio.io advantage: From treating symptoms to analysing causes

Versio.io solves this problem by shifting the focus from symptoms to changes. Instead of investigating a vague alert, you start with the exact change that caused the problem.

• Real-time change detection - Versio.io creates a "digital twin" of your entire IT landscape and detects every change to every configuration element down to the attribute level. The earliest sign of an incident is therefore not a drop in performance, but the change itself.
• Context through topology - Versio.io sees not only data points, but also their relationships. The platform automatically maps dependencies between all systems. With delta topology analysis, teams can compare the state before and after a change to immediately see what has changed - be it a database schema or a network configuration. This drastically reduces the mean time to knowledge (MTTK).
• Intelligent alerting - Versio.io's event management system automatically correlates events with contextual data in the CMDB. An alert no longer reads "Port 443 is down", but rather "Port 443 is down on “prod-web-srv-01” 5 minutes after its firewall configuration was changed by user “admin”." This eliminates noise and alert fatigue.

Stop chasing alarms - Start mastering change

The only sustainable way to achieve a radically lower MTTI is to gain control over what precedes every incident: change. Tools that offer comprehensive change monitoring are a necessity. Versio.io is the ultimate MTTI tool because it addresses the root cause of detection delays.
