Vendor Break-Glass Accounts

A cloud platform vendor maintained break-glass accounts for genuine emergency access , credentials stored in a physically secured envelope, with usage requiring dual authorization from the CISO and a designated deputy, with all usage triggering immediate SIEM alerts and post-use review. The design was appropriate. The implementation drifted. A security review triggered by an anomalous access alert found that the break-glass account had been used eleven times in the preceding six months. Investigation found that three of the eleven uses were genuine emergencies matching the intended purpose. The remaining eight were operational convenience uses: deployments running behind schedule where normal change approval would take too long, configuration changes needed outside business hours when the primary admin team was unavailable, and access needed urgently for a client presentation. None of the convenience uses had been declared as emergencies in the dual-authorization process , in each case, a single senior engineer had used the break-glass credential directly without the required second authorization. The break-glass account had become an emergency workaround for normal operational friction. Each use had full admin privileges, no session recording specific to the break-glass context, and no consequence that discouraged the next convenience use.

What are Break-Glass Account Risks, Really?

Break-glass accounts are high-privilege emergency credentials designed for situations where normal access pathways are unavailable and critical systems require immediate intervention , catastrophic lockout events, active incidents requiring admin access faster than normal workflows can provide, and disaster recovery scenarios where standard authentication infrastructure may be unavailable. They represent a deliberate security exception: accepting the risk of a standing, highly-privileged credential in exchange for the operational availability benefit of emergency access.

The design tension in break-glass accounts is structural: an account that must always be available for genuine emergencies cannot be revoked, cannot require complex activation steps, and cannot be governed through the same controls that apply to normal operational access , because those controls are exactly what the break-glass account is designed to bypass when they are unavailable. The security design accepts this tension by pairing the exceptional access with exceptional governance: strict physical security, dual authorization requirements, immediate alerting on use, and mandatory post-use review. The governance compensates for the standing privilege by making every use visible, documented, and reviewed.

The drift-to-default problem arises when the operational friction of normal access pathways creates incentive to use the break-glass credential for non-emergency situations. An engineer who needs urgent access and faces a two-hour approval workflow may see the break-glass credential as a faster alternative. If the consequences of that convenience use are minimal , an alert fires that generates a review that concludes the use was unauthorized but does not produce consequences , the incentive remains and the behavior recurs. Over time, the break-glass account acquires a secondary function as the path-of-least-resistance for time-sensitive access, while the governance designed for emergency use applies inconsistently or not at all to the convenience uses.

• Break-glass used for operational convenience , non-emergency uses of emergency credentials when normal workflows are slow
• Single-authorization bypass , dual-authorization controls bypassed when one party can access credentials independently
• No post-use review consequences , unauthorized break-glass use identified in reviews without consequences that deter recurrence
• Break-glass scope too broad , emergency credentials with broader privilege than the emergency scenario requires
• Break-glass in digital storage , credentials accessible digitally without the physical security that prevents casual access

Why this matters

Break-glass accounts matter for TPRM because vendors who manage customer environments have emergency access mechanisms for those environments , and those mechanisms may be subject to the same drift-to-default problem. A vendor break-glass credential for a customer environment that is occasionally used for deployment convenience creates customer risk: full admin access to the customer environment used without the change management, approval workflow, and session oversight that normal access would require.

The attacker value of break-glass credentials makes them high-priority targets. A break-glass credential provides admin access without the identity governance workflows that normal admin access requires , no approval, no time limit, potentially no session recording. An attacker who obtains a break-glass credential has admin access that bypasses every operational control designed to govern how admin access is used. The credential was designed to bypass those controls in emergencies. The attacker uses it to bypass those controls permanently.

Where most teams get this wrong

The most consistent failure is assessing break-glass design without assessing break-glass usage patterns. A well-designed break-glass process with poor enforcement produces a credential that is available for misuse under the cover of emergency access governance. The design describes what should happen. The usage pattern describes what does happen. Both require assessment.

• Assessing break-glass design without usage pattern review
• No consequence for unauthorized break-glass use , reviews without deterrence
• Break-glass use volume not assessed , frequency of use as a drift indicator
• Dual authorization enforcement not verified
• Break-glass scope not minimized , broader than emergency scenario requires

What good looks like

Mature break-glass governance programs enforce the design consistently , dual authorization enforced technically rather than through policy, use volume monitored as a governance signal, and unauthorized convenience uses producing consequences that deter recurrence.

• Technical dual-authorization enforcement , credentials cannot be accessed by a single party regardless of physical access
• Use volume monitoring , frequency of break-glass use monitored as a drift indicator
• Post-use review with consequences , unauthorized uses producing defined consequences
• Scope minimization , break-glass privileges scoped to minimum required for emergency scenarios
• Immediate credential rotation post-use , break-glass credentials rotated after every use

Tooling

PAM for Break-Glass , CyberArk, BeyondTrust

PAM platforms implement break-glass access with technical dual-authorization , credentials cannot be checked out without the required number of approvers, session recording is automatically enabled for break-glass sessions, and all access generates immediate alerts. For TPRM practitioners, asking whether break-glass access for customer environments uses PAM-enforced dual authorization rather than policy-only controls provides a specific technical enforcement question.

SIEM Alerting , Microsoft Sentinel, Splunk

SIEM integration for break-glass alerts ensures every use triggers immediate notification and review. For TPRM practitioners, asking whether break-glass use generates automated alerts with defined review requirements provides an enforcement monitoring question.

Governance challenges

The governance challenge with break-glass is the consequence gap. Reviewing unauthorized break-glass use and noting it as policy violation without consequences that deter recurrence creates a review process that identifies problems without resolving them. The governance resolution requires defining consequences for unauthorized use that are proportionate to the break-glass design's security significance.

• Ask for break-glass use frequency , total uses in the last twelve months
• Ask what percentage of uses were genuine emergencies
• Ask whether dual authorization is technically enforced
• Ask what happens when break-glass is used for non-emergency purposes
• Ask about credential rotation post-use

If you are a small team

Ask your managed services vendors for their break-glass use log from the last twelve months: how many times was the break-glass credential used, and for each use, was a genuine emergency declaration made with dual authorization? The ratio of genuine emergencies to total uses is the drift indicator. A break-glass credential used eleven times with three genuine emergencies has drifted significantly from its intended function.

• Ask for break-glass use count and emergency vs convenience breakdown
• Ask whether dual authorization is technically enforced or policy-only
• Ask whether break-glass credentials are rotated after every use
• Ask what consequences apply to unauthorized break-glass use

What to require

Ask directly:

"How many times was the break-glass account for our environment used in the last twelve months , and for each use, was a formal emergency declaration made with the required dual authorization?"

"Is dual authorization for break-glass access technically enforced , meaning a single individual cannot access the break-glass credential regardless of their physical access , or is it a policy control that depends on individual compliance?"

Expect as evidence

• Break-glass use log with emergency declaration status for each use
• Dual authorization technical enforcement confirmation
• Post-use credential rotation policy
• Consequence policy for unauthorized break-glass use

A vendor who confirms break-glass access is controlled should be asked for the use frequency and the ratio of genuine emergency uses to total uses. The design controls the credential. The usage pattern controls the behavior. Both require assessment.

How to evidence it

• Break-glass use log with emergency declaration records
• Dual authorization enforcement documentation
• Credential rotation post-use records
• Post-use review and consequence documentation

Key Takeaway

Break-glass accounts are emergency tools. They are also the highest-privilege credentials in the environment , full admin access, standing credential, designed to bypass normal governance controls. When operational friction creates incentive to use them for convenience, the emergency access mechanism becomes standing admin access without the accountability of normal admin provisioning. The design is correct. The enforcement is the question. Dual authorization technically enforced prevents convenience use. Dual authorization as policy-only is a reminder that motivated individuals ignore under deadline pressure. Ask for the use log. Count the emergencies. The ratio tells you whether the break-glass is a fire extinguisher or a preferred delivery route.
