What changes when identity turns the new perimeter

In recent years, the way companies protect their assets has changed radically. The traditional perimeter, focused on firewalls and VPNs, has given way to a new security concept: identity-based protection. When you talk about digital threats, what is at stake is not just the network, but who is behind each credential used to access it.

In this scenario, ITDR comes in, which stands for Identity Threat Detection and Response. More than a solution, ITDR represents a new mindset: monitoring, investigating and responding to threats that use identities as a gateway. While many organizations still focus only on access management, the most prepared have already evolved to a more mature and responsive model, where real-time detection and coordinated response are the standard, not the exception.

From prevention to active response: the leap that the ITDR promotes

IAM, IGA, MFA... all of these technologies are still fundamental, but they were not designed to identify and contain ongoing attacks. The role of ITDR begins exactly where traditional solutions stop. It comes into action when an attacker has already obtained valid credentials and tries to act as a legitimate user within the corporate environment.

It is at this point that the ITDR shows its differential: by crossing behavior patterns, schedules, devices, access contexts and relationships between systems, it manages to identify what would go unnoticed by other tools. That is, even when everything seems normal, the ITDR attaches signs of abnormality and acts before the damage is consolidated. This ability changes the game. Because it is no longer a question of just granting access, but of continuously monitoring how these accesses are being used.

Why ITDR is different from anything you've ever seen

Many solutions claim to protect identities. Few, in fact, are able to detect abuse in real time. ITDR does not replace tools such as SIEM or EDR, but complements them with an in-depth look at identity behavior. While a SIEM analyzes logs and large-scale events, ITDR specializes in individual connections, behavioral deviations, and risk patterns that signal credential abuse.

In addition, ITDR operates in layers invisible to traditional systems. It detects, for example, if an authentication token has been misused, if a service account has started accessing unintended systems, or if an employee has escalated privileges at atypical times. And the best thing: all this with the possibility of automatic response. From locking accounts to requiring additional authentication, the answers are agile and personalized.

The gains of those who have already adopted this new mentality

Companies that implemented ITDR with maturity reported not only increased safety, but also a significant reduction in incident response time. MTTR (mean response time) dropped dramatically in environments where ITDR was integrated into the IAM, IGA and SIEM ecosystem.

Another relevant point is the positive impact on audits and certifications. With detailed behavioral reports, complete audit trails and the ability to demonstrate the effectiveness of controls, ITDR becomes a great ally of compliance. Standards such as SOX, ISO 27001 and LGPD increasingly require that companies not only control access, but also verify that these accesses are being used securely.

Challenges that need to be faced for the ITDR to get it right

Despite the benefits, implementing an efficient ITDR is not simple. It requires a solid foundation of identity governance. This includes up-to-date data, well-defined roles, mature access review processes and, above all, integration with other security ecosystem tools.

In addition, the ITDR requires analytical capacity of the team. The interpretation of alerts, the configuration of the response playbooks and the fine-tuning of the detections need to be done with criteria. This requires time, training and alignment with the business areas. But when executed well, the return in security, visibility and confidence is incomparable.

And what comes next?

The future points to an even smoother integration between ITDR, AI and automation. There are already tools that use machine learning to adjust, in real time, behavior-based risk parameters. That is, the more the system operates, the more accurate it becomes. This reduces false positives and increases operational efficiency.

In addition, with the growth of non-human identities (such as APIs, bots and system integrations), the role of ITDR tends to expand. After all, protecting human users is important, but protecting automatic flows that operate silently in the background is vital to ensure that there are no blind spots.

The role of vennx in the adoption of advanced ITDR strategies

At Vennx, we understand that it is not enough to offer tools. It is necessary to deliver complete solutions, with integration, intelligence and real responsiveness. That is why our ITDR projects are always connected to GRC strategies, continuous auditing and control automation.

Backed by proprietary technologies and dedicated experts, we help companies map their identity risks, configure intelligent response policies, and create a more resilient operation. The focus is not just detecting. It is to act. Because security that does not respond, does not protect.
