Email Security
Block phishing, malware and business email compromise before they reach a user's inbox.
Email is still the most common way attackers get into a business
Email security filters malicious messages, unsafe attachments, dangerous links and impersonation attempts before they ever reach a user. Done properly, it tunes protection to your real senders and risky users.
- Reduces phishing, malware and business email compromise
- Protects your finance and leadership inboxes
- Keeps genuine email flowing when threats spike
- Policies tuned to your business, not left on defaults
- High-risk users have extra protection
- Quarantine is reviewed and false positives are cleaned up
Are your email security settings tuned to your business, or just running on defaults?

Understanding email security
Email is still the number one attack vector. Default Microsoft 365 anti-spam catches the obvious stuff; modern attackers don't send obvious stuff. We layer Microsoft Defender for Office 365 with the policy and tuning that actually stops impersonation, attachment-based malware and supplier compromise - and we triage what gets through.

- ISO 27001:2022 Annex A controls
