What Your Email Security Audit Covers

Practical email risk visibility

SPF, DKIM, DMARC

Reduce Domain Spoofing

Email authentication is one of the first places attackers look for weakness. Perimetra reviews SPF, DKIM, and DMARC alignment to see whether your domain is properly set up to reduce spoofing and impersonation attempts.

You receive plain-English findings that explain what each record does, where gaps exist, and how changes can improve trust in messages sent from your domain. The result is clearer control over email identity and better protection for client-facing communication.

Access Review

Control Mailbox Access

Compromised or poorly managed mailbox access can create quiet business risk. Perimetra reviews account permissions, forwarding rules, shared mailboxes, admin access, and risky login patterns that may expose client data or sensitive firm workflows.

The audit highlights access that should be reviewed, removed, or better protected. You get practical recommendations that help limit unnecessary exposure, support stronger account administration, and improve visibility into who can access critical email resources.

Phishing Controls

Find Phishing Exposure

Phishing risk is not limited to obvious scams. Perimetra evaluates how your current email environment handles suspicious links, lookalike domains, malicious attachments, and messages designed to pressure staff into payment or credential mistakes.

The review connects technical controls to real business impact. Findings show where filtering, sandboxing, user warnings, and security awareness can improve. That gives your team a clearer path to reduce inbox risk without slowing down normal communication.

Microsoft 365 Review

Strengthen Cloud Email

Microsoft 365 includes many useful security settings, but they are not always configured for the way a firm actually works. Perimetra reviews the email-related controls that affect identity, mailbox protection, alerts, and administrative visibility.

You receive a clear summary of settings that should be strengthened, simplified, or monitored more closely. The goal is to help you get more value from the tools already in place while reducing gaps that can affect business continuity and client trust.

Risk Reporting

Get Clear Audit Proof

An audit should produce more than a technical checklist. Perimetra delivers reporting that explains exact findings, why they matter, and what action should happen next. Recommendations are prioritized so leadership can understand which changes create the most immediate value.

This documentation can support internal decision-making, cyber insurance conversations, and compliance-readiness efforts. It is built for busy firms that need practical clarity, not dense security language that never turns into action.

Remediation Support

Move From Audit to Action

Once gaps are identified, Perimetra helps you move from review to improvement with speed over bureaucracy. Depending on your needs, that may include email security gateway setup, anti-phishing controls, attachment sandboxing, security awareness training, monitoring, and monthly threat reports.

Qualified firms can start with a 30-day proof-of-value to see the service in action before committing. You get a dedicated partnership model focused on practical outcomes, fast deployment, and proof in every report.

Know Where Your Email Security Stands

Email is where many sensitive-data firms carry the most daily risk. Client records, invoices, wire instructions, case files, patient details, tax documents, and password resets all move through inboxes. An Email Security Audit gives you a clear picture of how well those workflows are protected.

Perimetra reviews the controls that matter most: email authentication, anti-phishing settings, attachment handling, mailbox access, forwarding rules, security alerts, and reporting visibility. The goal is not to overwhelm you with technical noise. It is to show what is working, what needs attention, and which fixes create the fastest risk reduction for your firm.

A Practical Review of the Controls That Matter

A practical audit should turn uncertainty into a prioritized action plan. Perimetra focuses on the settings, workflows, and user risks that affect business continuity, compliance readiness, and client trust.

Email authentication review, including SPF, DKIM, and DMARC alignment
Mailbox access checks for risky permissions, forwarding, and account exposure
Anti-phishing and attachment protection review for safer daily communication
Microsoft 365 security configuration review where applicable
Plain-English reporting that explains findings, impact, and next steps

You get guidance built for SMB reality, not a generic checklist detached from daily operations.

Turn Email Findings Into Actionable Protection

An email audit is most valuable when it leads to action. Perimetra helps you connect each finding to a clear business outcome, such as fewer spoofed messages, stronger account controls, better documentation, and improved visibility into what your users receive.

For law, medical, and accounting firms, that clarity supports more than IT hygiene. It helps protect client trust, supports audit-ready documentation, and gives leadership a practical way to make informed security decisions. If ongoing protection is needed, Perimetra can help move quickly from assessment to deployment with onboarding, setup support, monthly threat reports, and access to the partner portal.
