Identity-first incident response

Stop the incident,
never the business.

Stop attacks in minutes, not days. Enforce controls instantly through identity, isolate compromised accounts, and stop lateral movement before an incident becomes an outage, without shutting the business down.

The Silverfort Identity Security Platform

One platform to contain incidents at the identity layer.

The fastest, simplest way to contain and respond to attacks.

Silverfort puts identity at the center of incident response. See authentication activity and enforce controls inline, at runtime, from a single platform. Reach the systems your EDR and other security tools can't. Contain faster. Respond faster. Recover faster.

Contain in minutes. Recover in hours.

A policy change, not an engineering project. Reduce MTTR from weeks to hours.

Keep the business running.

No emergency GPOs. No pulled cables. A few policy toggles stop the spread.

Every incident leaves you stronger.

The controls you use to stop an attack stay in place to prevent the next one.

Full coverage, even where EDR can't reach.

Service accounts, NTLM, OT/IT, unmanaged systems—the paths attackers actually use.

An identity-first incident response lifecycle

Silverfort aligns with the IR lifecycle while reordering it around identity-first containment and visibility.

Preparation

Close the gaps attackers exploit before an incident strikes. Enforce MFA across all users (including admin accounts and tools), eliminate standing privileges, and establish authentication policies that can be tightened instantly.

Detection

Surface threats early. Abnormal access behavior, lateral movement attempts, and policy violations give your team the signals to immediately identify an emerging breach, and discover which identities are compromised and how attackers are moving.

Containment

Immediately restrict access for high-risk users, privileged accounts, and service accounts with virtual fences, MFA challenges, or deny policies. Stop malicious spread immediately, without waiting for every compromised account to be uncovered.

Eradication

Remove attacker footholds by revoking compromised credentials and eliminating unauthorized access paths. Use unified authentication logs to confirm that no persistent access remains across users, devices, or integrated systems.

Recovery

Replace temporary lockdown controls with durable access policies and restore normal operations securely. Validate that all restored accounts and service connections meet your Identity Security baseline across your entire identity estate.

Lessons learned

Use posture insights and the full attack timeline—from patient zero to every affected system—to understand how access was abused, close structural gaps, and harden your identity estate against the next attack.

See it. Stop it. Come back stronger.

Use identity-first incident response to see every compromised access path, shut down malicious activity without disrupting legitimate users, and lean on the attack itself to sharpen your defenses—all from the same platform.

See every compromised identity and access path

Start with a unified view of your identity activity.

Contain the attack without killing productivity

Lock down malicious access in minutes.

Turn containment into detection

Let attacker behavior expose compromised identities.

Accelerate recovery and harden identity posture

Recover on your terms, not the attackers

Built for any incident response scenario

Ransomware and lateral movement

Stop propagation by enforcing MFA and segmentation on the same tools attackers use to spread—RDP, SMB, PsExec, PowerShell, WMI, and more.

Compromised admins and infrastructure

Lock down domain admins, admin accounts, and identity infrastructure access without taking domain controllers offline.

Exposed service accounts and NHIs

Discover and virtually fence service accounts so they can’t authenticate outside their normal behavior, preventing lateral movement and privileged escalation.

Work alongside your IR team—or ours.

Contain faster, without changing how you respond. Silverfort integrates directly into your environment and becomes an active control layer during the incident, whether you’re working with:

FAQs

What is identity-first incident response?

Identity-first incident response is an IR approach that treats identity—not endpoints or network—as the primary control point for containing an attack. Instead of starting with device isolation or network segmentation, teams use authentication signals and access policies to detect compromised accounts, stop lateral movement, and cut off attacker access in real time.

How is identity-first incident response different from traditional IR?

Traditional IR starts at the endpoint or network layer, which means attackers can keep authenticating and moving laterally while responders are still investigating. Identity-first IR flips that order: it uses the identity layer to immediately restrict access for compromised accounts, then investigates and remediates from there, shrinking the window attackers have to spread.

Why does identity-first incident response matter for AI attacks?

AI-powered attacks compress the time between initial compromise and lateral movement from hours to seconds, so IR processes built around manual endpoint response can’t keep pace. Identity-first containment enforces policy changes, like MFA challenges and access denials, inline and at runtime, fast enough to match AI-speed privilege escalation.

Can identity-first incident response contain an attack without shutting down the business?

Yes. It works through targeted policy changes rather than blunt measures like pulling network cables or issuing emergency GPOs. By enforcing MFA or denying access only for the specific users, admins or service accounts showing risk, legitimate users and business operations can continue uninterrupted.

What systems does identity-first incident response cover that EDR can't reach?

It extends to service accounts, NTLM traffic, OT/IT environments, and unmanaged systems—the authentication paths attackers actually use to move laterally, many of which sit outside traditional endpoint detection and response coverage.

Does identity-first incident response replace my existing IR team or tools?

No. It’s designed to integrate into your existing response process, whether that’s an internal SOC or an external IR firm, adding identity-layer containment and visibility as an active control during the incident rather than replacing the team running it.
