Business-focused solution

Email Security & Phishing Protection

Email protection combines technical controls with identity safeguards and clear business processes. AOS helps UK organisations assess their mail environment and consider layered protection for Microsoft 365 and Google Workspace.

The business challenge

Why this matters

Attackers exploit trust, urgency and familiar business processes. A convincing message may impersonate a supplier, request payment changes or capture credentials, even when a mail filter is in place.

Potential business impact

Email compromise can lead to unauthorised access, payment diversion, data exposure and disruption to customer or supplier relationships. Filtering helps but does not replace identity security and independent verification.

Common warning signs

  • •Payment or bank-detail changes are verified only by replying to email
  • •Users report suspicious messages inconsistently
  • •Mailbox forwarding rules and external access are rarely reviewed
  • •Domain authentication records have no clear owner
  • •Security teams cannot quickly investigate suspected mailbox compromise

AOS approach

A practical route from need to action

Review the email platform, current licences, mail flow, identity controls and reporting process. Identify the protections already included, then scope additional filtering, impersonation defence, authentication and awareness measures as needed.

How a solution may work

  1. 01Map mail platforms, domains, mail flow and current protections
  2. 02Review identity, admin access, forwarding and reporting
  3. 03Agree technical controls and any DNS/configuration changes
  4. 04Confirm user communications and incident escalation steps
  5. 05Review outcomes and adjust protections within the agreed service

Potential solution components

  • Anti-phishing and malicious-link/attachment controls
  • Business email compromise and impersonation protection
  • Spam and malware filtering
  • SPF, DKIM and DMARC review where in scope
  • MFA, mailbox monitoring and user reporting procedures

Technology options to consider

  • Microsoft: Defender for Office 365 and Microsoft 365 native controls may be assessed against current licences
  • Check Point: authorised UK partner option for email and collaboration protection
  • TitanHQ and Barracuda: email security technologies in the wider ecosystem; exact product fit and availability must be confirmed

Only Check Point authorised UK partner status is confirmed. Other vendor references do not imply AOS authorisation, resale, product availability or a specific integration. Vendor selection and capabilities are verified against current documentation during scoping.

Who benefits

Suitable organisations

Useful for organisations using Microsoft 365 or Google Workspace, especially those handling confidential information, processing payments or relying on email for supplier and customer communication.

Engagement options and boundaries

  • • Free 30-minute cybersecurity review can include email security and phishing exposure
  • • Scoped email-security configuration and implementation options
  • • Managed filtering or response only where the actual provider, hours and boundaries are confirmed
  • • Security awareness or phishing simulation, if offered, requires separately confirmed scope and appropriate internal approval

Frequently asked questions

Will email security stop every phishing message?

No filter catches everything. Combine technical filtering with MFA, payment verification, reporting and incident preparation.

Do we need to replace Microsoft 365 or Google Workspace?

Usually not. Additional controls can complement the existing mail service, subject to licensing and mail-flow design.

Can you assess domain email authentication?

SPF, DKIM and DMARC can be reviewed as agreed. Changes should be coordinated with the domain and email administrators.
