What We Do for You
- Harden your mail platform and authentication records.
- Deploy filtering for phishing, impersonation and malicious attachments.
- Protect Teams, Slack, SharePoint and shared drives.
- Set up reporting so staff can flag a suspicious message in one click.
- Review what got through each month and tighten the rules.
How this is bought: Bought as a defined project to set it up, then a monthly managed service to run it. Build an estimate for your case.
Platforms We Work With
Check PointMicrosoft
These are the platforms we work with on client estates. Where a client already owns a different platform, we work with theirs - ARRIX is not tied to any one vendor.
Our Approaches Explained
SPF, DKIM and DMARC
Records that prove your mail is really yours, so others can reject forgeries sent in your name.
Business email compromise defence
Detecting the invoice-change and payroll-diversion messages that no attachment scanner catches.
Attachment and link protection
Files opened in isolation and links rechecked at the moment of click, not only on delivery.
Collaboration platform protection
The same scanning applied to chat, file shares and cloud drives.
User reporting and takedown
A one-click report button, with the reported message removed from every other inbox.
The Standards We Work To
DMARC (RFC 7489)M3AAWG sending practiceMicrosoft 365 / Google Workspace security baselines
We follow the structure and controls these standards describe. We do not claim to be certified against them - where you need a formal certificate, we prepare the evidence and an accredited body performs the audit.
