Your organization just got hit with a ransomware attack. Your cyber etIT departments are scrambling to get your incident response plan started etoperational. All of a sudden, everyone realizes that they cannot log in to anything.Active Directory (AD) must be offline!? Your organization’s authentication etauthorization tools are impacted.
After hours of triage etassessing the size of this problem, your cyber incident response team reports that restoring foundational AD etauthentication etauthorization services will take over a week, if everything goes well.
You thought your resiliency plan with AD backups eta SaaS identity platform was sufficient. But even with SaaS in the mix, recovery is complex etmanual, delaying the path back to minimum viable operationswhen time matters most.La résiliencemeans you can restore authentication etauthorization quickly etpredictably in a trusted way, whether the disruption is malicious activity, an outage, or an accidental misconfiguration.
Understanding the Threat
Attackers target AD because it’s the identity control plane. Once they get a foothold, they’ll often establish persistence by creating shadow or backdoor accounts, then harvest credentials, etescalate privileges. With elevated access, they laterally move across systems etapplications, sometimes staying quiet long enough that the first clear signal is when authentication starts failing.
They gain a wealth of knowledge of the organizations network, people, etapplications. And when they’re ready to maximize impact, they can encrypt or corrupt the AD forest, disrupting logins etcomplicating recovery across the environment.
Why Identity (etWhy AD First)?
It’s common for an organization’s identity stack, especially AD etEntra ID, to become complex over time. Forests expand, permissions sprawl, legacy policies accumulate, et“good enough” processes often turn into long-term security drift. That complexity creates blind spots, etdefenders lose crisp visibility into how roles, privileges, etpolicies evolve.
And it’s never “just AD.” Identity is an ecosystem: identity governance etaccess solutions (IGA), privileged access, customer identity, identity providers, authentication databases, etsingle sign-on all connect back to the same truth. That’s why identity incidents (eteven everyday misconfigurations) can cause outsized disruption compared to many other infrastructure failures.
The recovery challenge is where most plans get exposed. Even with backups, forest recovery is a multi-step, high-stakes process, where guidance for manual recovery can involve 50 to 100 (or more) individual steps etcan take days to weeks, depending on environment complexity etpreparedness.
The real question isn’t “do we have backups?” it’s “can the teams leverage the backups to cleanly execute under pressure, ethave runbooks been tested etverified so recovery doesn’t become an error‑prone scramble at the worst possible time?”
La solution
The need to have a recovery plan is great. It needs to be tested etverified. Organizations need to know etunderstetthat your identity management platform is the No. 1 target for cyber criminals etattacks. It needs to be protected as such. It needs to be backed up, tested, etverified it can be recovered. This includes:
- Backups of AD, Entra ID, etIGA platforms.
- Tested etverified recovery plans.
- Isolated recovery environments etCleanroom.
- AD recovery workflow etautomation.
Strong identity governance etmonitoring are still critical, but they’re only part of the equation. You want the ability to detect suspicious identity behavior early, contain it fast, etrecover with confidence when something changes that shouldn’t (whether it’s malicious activity or an accidental modification that breaks authentication).
That also means you need to integrate identity account etuser activity into SecOps etcontinuously watch for signals like unauthorized account creation, privilege changes, etabnormal authentication patterns, ethave a recovery path that’s proven, repeatable, etclean.
Commvault etDeloitte: A Partnership for Identity La résilience
La résilience des identités is a business challenge that requires strong governance, processes, controls, etenabling technology. That’s why Deloitte etCommvault have partnered to deliver comprehensive identity protection, recovery, etresilience programs that organizations can trust when it matters most.
Deloitte brings deep expertise in cyber risk, enterprise resilience, etidentity etaccess management to help Fortune 100 to 1000 organizations design, implement, etoperationalize identity resilience programs.
These programs help clients assess security posture, improve detection etresponse capabilities, etdefine minimum viable company requirements, etthen build tested, verified recovery plans with clear timelines etaccountability across business etIT stakeholders. Deloitte turns identity resilience into an executable program with runbooks, testing, etreadiness, so teams know what “prepared” looks like under pressure.
Commvault makes resilience programs operational with integrated protection etautomated recovery workflows across identity systems, plus Commvault AirGapetCleanroomto support repeatable, clean, validated recovery when it matters most. Commvault provides the technology foundation with identity resilience capabilities that include:
- Protection for critical identity systems, including AD etEntra ID, point-in-time comparison etrollback support for unwanted or accidental changes.
- Auditing etdetection to surface suspicious modifications early (who changed what, etwhen), helping reduce the window for attackers to spread or persist.
- Automated recovery workflows, including forest-level recovery automation, to help reduce the manual burden eterror risk during identity restoration.
- Commvault Cleanroom to help validate identity recovery in isolation before reintroducing trust back into production.
- Commvault AirGapto help maintain immutable, air-gapped backup copies, creating a protected foundation that supports clean recovery etcleanroom testing when identity (or the environment around it) can’t be trusted.
Take Action
If you want to pressure-test your cyber recovery readiness, start with a Deloitte Active Directory Workshop to map dependencies etproduce a clear, actionable plan to recover AD etworkloads to production. Then validate it the right way: using Commvault to rehearse recovery in a cleanroom before you ever need it in a real event.
For organizations ready to take the next step, we can extend this into a 30-day pilot that puts clean recovery ettesting into motion with real artifacts etmeasurable outcomes.
