Rolling Out Email Error Prevention in Report Only Mode

Turning on a control that talks to every sender needs a plan that doesn’t annoy anyone. A warning that appears too often gets ignored, and a control that people ignore protects nobody. Email error prevention succeeds or fails on how it’s introduced.

Kiteworks Agent and Human Error Prevention (AHEP) gives administrators a clear way to do this. Policies can run in Report Only mode, which evaluates and logs every message without showing a single alert. The risk is skipping that stage, because a new policy defaults to On and is enforced the moment it’s saved.

This article walks through the rollout in order: preparing the platform, creating policies, reading the baseline, and moving from Suggest to Warn with evidence in hand.

Executive Summary

A sensible AHEP rollout takes five stages. Confirm the platform prerequisites, create the policies with status set to Report Only, read the baseline for a few weeks, pilot Suggest with a high-value group, and move selected policies to Warn where the data supports it. Existing Kiteworks customers need no additional vendor, because AHEP is a capability of the Data Policy Engine on the platform they already run. The outcome is a set of policies tuned on your own mail, a pilot group that has seen the alerts in context, and an audit trail for your security and privacy leads.

Key Takeaways

1. Check the platform prerequisites before you configure anything. AHEP needs release 9.5 and the Validation Service on the containerised services layer, which Kiteworks technical support enables on request.
2. Set the status to Report Only before you save. A new policy defaults to On and is enforced immediately, so the safe path starts with the status field, not the threshold.
3. Report Only gives you a baseline without user impact. Every message is evaluated and every detection is logged, so a few weeks of data show where the risk sits.
4. Suggest first, Warn where the data supports it. Suggest informs the sender without getting in the way, and Warn asks for a conscious decision once your numbers justify it.
5. Know client coverage before you promise anything to a department. Alerts work in the Kiteworks Web App and Outlook Classic, so plan around users on other clients.

Preparing the Platform for AHEP

Before any policy exists, the platform has to be ready. AHEP is available from release 9.5, so customers on earlier versions need the upgrade first and should plan the rest around their upgrade window. The Validation Service that evaluates messages runs on the Kiteworks containerised services layer (RKE2), on at least one application node, and Kiteworks technical support enables it.

Raising the Request

Open the request through the Kiteworks community portal before you configure anything. Policies created without the service behind them can’t do their job, and discovering that after announcing a pilot to a department is an avoidable embarrassment.

Roles You Need

Creating policies in the Data Policies app requires the System, Application, Compliance or Policy Manager role, or a custom role with Data Policies access. Check who holds those roles in your organisation early, since the person who owns the project often isn’t the person who can create the policy.

Creating Policies and Starting in Report Only

In the Data Policies app, choose New Policy and then Agent and Human Error Prevention, or start from the AHEP template, which preselects the BCC recommendation. Change the status to Report Only before you save, because the default is On. For the BCC policy, set the external-recipient threshold at the same time.

Reading the Baseline

Let the policies run for a few weeks. Every message is evaluated and every detection is logged, and no sender sees an alert. Review detections per policy, the false positives and the senders and teams involved. Compare the numbers with your incident log and with what your DLP flagged in the same period. The baseline tells you which policy deserves attention first and which threshold needs adjusting.

Two Details That Save Time

Detection works best when user profile names follow a standard format, such as First Last or Last, First, and when business addresses look like firstname.lastname@company. That matters most for the personal-address policy, which compares the recipient with the sender’s identity.

Moving from Suggest to Warn

Take the highest-value policy and move it to On with the Suggest directive for a pilot group. Legal and finance are sensible places to start, since a misdirected message costs more there. Suggest informs the sender without getting in the way, so the pilot shows how people react without adding friction.

When Warn Makes Sense

Warn requires the sender to resolve or dismiss the alert before sending. Move selected policies to Warn where the data supports it. Dismissals are logged, so override rates show you where thresholds or training need work. A department that dismisses every BCC alert is telling you something about the threshold.

Taking the Evidence to Your Security and Privacy Leads

AHEP policies appear in the Report by Policy list in the Audit Log and Reports app. That gives your CISO and data protection officer a record of detections, directives and decisions, built from your own mail rather than from a vendor’s estimates.

Switching On Error Prevention Across the Kiteworks Data Control Plane

Rolling out AHEP isn’t a separate project with its own vendor, console and log. It’s an extension of the Kiteworks Data Control Plane you already operate. The Data Policy Engine governs email, file sharing, SFTP, MFT and forms, and AHEP adds recipient checks for data in motion at the point where people and AI agents choose where it goes. Events land in a tamper-proof audit log that can feed your SIEM tooling, and the work complements your existing DLP and IAM tooling.

If you’re a current Kiteworks customer, schedule an enablement session with our team. We’ll plan the 9.5 upgrade, the Validation Service request and your Report Only baseline together, so the first alert any sender sees is one you have already tuned.
