Email is still the easiest way into a business. Our email security services layer anti-phishing, business email compromise defense, sandboxing, impersonation protection, and spam filtering services across Microsoft 365 and Google Workspace, so the inbox becomes a controlled surface rather than the open door attackers count on.

Scalable Partnership

How We Onboard and Secure Email & Collaboration
Native email defaults are a starting point, not a security program. At AppStudio we harden Microsoft 365 and Google Workspace with layered controls and then operate them, because a policy set nobody tunes drifts back to open within a quarter.
Email security sits inside our cybersecurity services and MSSP programs, and it only works when identity, encryption, and DLP move together with it.
The outcome is fewer successful phishes, cleaner collaboration risk from email security solutions that stay tuned, and reporting your leadership can actually follow.

Trusted by Teams Tired of Treating Phishing as Inevitable
You cannot train your way out of every crafted BEC attempt. What actually moves the number is controls on the inbox, monitoring behind them, and a response path when a message slips through. Our email security services put all three around Microsoft 365 and Google Workspace so a single crafted message stops being a company-wide incident.
Encryption, spam filtering, impersonation defense, and user reporting are run as one operated program rather than a pile of settings nobody revisits. Classification and identity move with it, so the mailbox that holds your most sensitive mail is also the one watched most closely, and leadership gets a monthly read on what was stopped instead of a surprise after the fact.
