What is access certification?

Access certification—also called access review or user access certification—is a formal process where an organization's authorized certifiers (usually managers or business owners) review and certify the access rights of users in their area of responsibility.

The certifier answers: "Are these users supposed to have this access?"

If the answer is yes, the access is approved. If the answer is no or uncertain, the access is flagged for review or removal.

It's one of the core steps in a user access review, and it's where most of the manual work happens.

Why access certification matters

Access certification creates accountability. It forces authorized decision-makers to explicitly confirm that each user's access is appropriate. Without it, you have access that's never been validated—access that no one is accountable for.

This is critical because:

• It's a compliance requirement. PCI DSS, HIPAA, HIPAA, ISO 27001, SOC 2, and SOX all require access reviews. Access certification is how you evidence that review. Without certification, you fail audit.
• It's your primary control against inappropriate access. Most insider threats and unauthorized access come from someone who had access they shouldn't have. Certification is your control to catch and remove that access.
• It reduces your attack surface. Each unnecessary access is a potential attack vector. Certification helps you identify and remove the access that's not needed.
• It creates accountability. When managers certify that access is appropriate, they're accountable for that decision. This drives better decision-making and creates an audit trail.

Access certification is foundational to a mature access governance program.

How access certification works

1. Scope definition

Define who needs to be certified and what access. Usually, this is all users across all systems, but you might start with a department or critical systems.

2. Data collection

Pull user access data from your systems. This is usually done via API or exports from each system, then consolidated into a standard format.

3. Certifier assignment

Assign each user or group of users to a certifier—usually a manager, team lead, or system owner. The certifier is responsible for reviewing and certifying their assigned users.

4. Certification request

Send certification requests to certifiers. This might be via email with spreadsheets, a web form, a portal, or a specialized access certification tool.

5. Certifier reviews and certifies

The certifier reviews each user and their assigned access and answers: "Is this access appropriate?" They certify (approve) or reject each user/access pair.

6. Tracking and escalation

Track who has and hasn't certified. Send follow-ups to incomplete certifications. Escalate late or missing certifications to managers and executives.

7. Remediation

For any access that was rejected or flagged, work with system owners to remove or modify the access.

8. Evidence and reporting

Document the entire certification process: who certified what, when, and what decisions were made. This is what auditors care about.

Without a specialized tool, most of these steps happen in spreadsheets and emails.

The challenges with manual certification

Manual access certification is painful:

You send a spreadsheet to a manager with 500 lines of access records, and they click "approve all" without reading a single line. Certification without attention is just theater.

Managers are busy, and certification requests are tedious. You send them an email with a spreadsheet. Half don't respond. You send reminders. Some respond 3 months late. You're tracking this in another spreadsheet.

You pull data from System A on Monday, System B on Wednesday, System C the next Monday. By the time you consolidate it, the data is stale and inconsistent. And when you send it to certifiers, it's already out of sync with reality.

If a certifier rejects access for a user, you now have to track which IT person needs to remove it, follow up to confirm it was removed, and update your records. Multiple teams, multiple tickets, multiple follow-ups.

Auditors want evidence: Who certified what? When? What was their finding? What action was taken? Manual certification generates minimal evidence, and you end up in a back-and-forth with auditors for months.

How Zluri helps with access certification

Zluri automates access certification by:

• Automatically pulling user access data from every application in your SaaS stack. No manual exports, no spreadsheets, no data inconsistencies.
• Creating certification campaigns where certifiers review access via a web interface (not spreadsheets), with rich context about each user and why they have access.
• Routing certifications intelligently so the right certifier reviews each user. Zluri understands who manages whom and routes accordingly.
• Tracking and reminding automatically. Zluri sends reminders to non-responsive certifiers and escalates to managers and executives when certifications are overdue.
• Enforcing attestation. Certifiers can't just click "approve all"—they have to interact with and acknowledge each access record, creating genuine accountability.
• Generating evidence and audit trails. Zluri logs every certification decision with timestamps and creates reports for auditors. No digging through spreadsheets.
• Automatically remediating. When a certifier rejects access, Zluri can automatically submit tickets to remove that access and track the remediation.

This turns access certification from a painful, manual, theater-like process into an efficient, documented, auditor-friendly control.

Summary

Access certification is the process where authorized decision-makers formally certify that user access is appropriate. It's a compliance requirement and your primary control against inappropriate access.

Manual certification is painful and generates minimal evidence. Automated certification with a tool like Zluri creates accountability, efficiency, and the evidence auditors need.
