Email Filtering Implementation Evidence

Auditors look for configuration exports from your email provider showing active anti-spam and anti-malware policies, quarantine logs demonstrating the system is catching threats, and lists of allowed domains or IPs to ensure they are justified. Tools like WatchDog Security's Compliance Center can help link each export and log sample to the relevant control and keep an exportable evidence package ready for audits.

Take screenshots of the administrative dashboards showing rule enforcement or export the policy settings via command line tools. Ensure the evidence captures the date, time, and the specific rules configured to block malicious content.

Retain summary reports of blocked threats, quarantine access logs, and administrative audit logs showing any changes to filtering rules. Retention periods should align with your organization log management policy, typically spanning 90 days to one year. WatchDog Security's Compliance Center can help track retention expectations per control and centralize approved log samples alongside configuration exports.

Generate a threat protection report from your email administrative portal spanning the last 30 to 90 days. This report should show the volume of messages categorized and blocked as phishing, malware, or spam.

Capture the anti-spam, anti-malware, and anti-phishing policy settings pages. Ensure the screenshots show that the policies are toggled on, apply to all active users, and have strict actions defined like routing to quarantine or rejecting.

Provide access logs or ticketing system exports that track when security administrators or users review quarantined items. Document the process for releasing legitimate emails to show it is controlled and monitored. WatchDog Security's Compliance Center can be used to store the quarantine review procedure and attach supporting records so reviewers can confirm consistency over time.

Include results from benign phishing simulations or third-party penetration tests that attempt to send simulated malicious payloads. The results should confirm that the filtering system successfully blocked the test emails.

Maintain a formally reviewed document or ticketing queue that records every requested exception. Each entry must include a business justification, the specific sender or domain allowed, and the approval of a security administrator.

The policy is a governance document dictating that email filtering must be used and defining the required rules. The evidence consists of technical configurations and logs proving that the policy is actually implemented and working in the environment.

Evidence must encompass active configuration settings, recent threat mitigation reports, documented allowlist exceptions, and proof that filtering mechanisms cover all organizational users and domains without unauthorized bypass capabilities.

A GRC platform can standardize what evidence to collect and keep configuration exports, screenshots, and mail security logs linked to the control they support. Tools like WatchDog Security's Compliance Center can map this evidence to multiple frameworks and generate exportable evidence packages for audits. WatchDog Security's Secure File Sharing can also help teams share sensitive configuration exports with auditors using access controls and audit logs.

Automation typically combines scheduled exports from your email provider with a central repository that enforces naming, ownership, and review workflows. Tools like WatchDog Security's Compliance Center can help teams track required evidence, assign owners, and maintain an audit-ready package over time. WatchDog Security's Trust Center can also help publish approved evidence to a customer-facing portal when you need to respond to security questionnaires.
