Email Security and Continuity Enhancements
Learn how we are upgrading our email protection systems to provide stronger security with minimal disruption to your daily workflow.
Why We're Upgrading Email Protection Now
Email remains the primary attack vector for business compromise, accounting for over 90% of successful cyberattacks. We've observed a significant increase in sophisticated phishing attempts targeting our managed clients — attacks that bypass traditional signature-based filtering by using newly registered domains, compromised legitimate accounts, and AI-generated content that evades pattern detection. Our current email security stack has served well, but the threat landscape demands a more advanced approach. We're implementing these enhancements proactively, before any client is impacted.
What's Changing: Enhanced Filtering and Continuity
We're deploying an advanced email security gateway that adds multiple layers of protection. Inbound messages now pass through URL rewriting that checks links at click-time (not just delivery-time), attachment sandboxing that detonates files in an isolated environment before delivery, and impersonation detection that flags emails spoofing executive names or known vendor contacts. We're also implementing email continuity — if Microsoft 365 experiences an outage, a secondary mail flow automatically activates so your team can continue sending and receiving email through a web portal. Once the outage resolves, queued messages sync back seamlessly.
What You'll Notice (and What You Won't)
For most users, the transition will be invisible. Email will continue to arrive in Outlook as normal. The only visible change is that external links in emails will be rewritten to route through our security gateway — when you hover over a link, you'll see a security URL prefix instead of the direct destination. This is normal and expected. Attachments may occasionally take 30-60 seconds longer to arrive as they pass through sandbox analysis. If the system flags a suspicious message, you'll receive a notification with options to release or report it. We've tuned the sensitivity to minimize false positives while maintaining strong protection.
Timeline and Support
The rollout will proceed in phases over two weeks. Week one covers email filtering and URL protection — this is a backend change with no user action required. Week two adds attachment sandboxing and the email continuity failover, which will be tested during a scheduled maintenance window. All managed clients will receive a brief notification before their environment is migrated. If you experience any unexpected email behavior during the transition — delayed messages, incorrect flagging, or access issues — contact our support team immediately. We're monitoring all environments closely throughout the rollout to catch and resolve any issues within minutes.
