Stronger Email Security Starts with the Right Configuration
Stop phishing, spoofing, BEC and spam threats before they reach your users by tuning Mimecast properly.
Whether you've been running Mimecast for years or inherited a setup, configuration drift and misconfigurations have most likely eroded your protection, performance, and user experience. Our expertise, developed over decades of working with Mimecast, helps you assess, tune, and align your Mimecast setup to deliver on its full potential—without selling you more licenses or features you don't need.

When Email Security Stops Being Seamless
Over time, even well-configured services will become misaligned with best practice and the changing threat landscape. You'll know this has happened when you start noticing:
- An increase in spam or phishing emails making it through to your users
- Delays in email delivery—especially to or from external partners
- Attachments and URL sandboxing not being blocked/let through as expected
- Users or admins encountering policy errors
- Security or compliance teams struggling with audits or visibility gaps
- Legacy configurations leaving you vulnerable to new threats
The result? An environment that technically works, but quietly exposes the business to avoidable risks or inefficiencies.
A healthy Mimecast estate builds confidence and trust.
- Email just works for your users, no spam, no phishing, no BEC, no delivery delays
- False positives are rare, and you can trust the system
- Policies are clear, aligned to business needs, and easily explained
- Troubleshooting becomes easier so Admins and analysts can quickly take action
- Your configuration matches Mimecast's recommended best practices, without unnecessary complexity
We help you get there.
