CyberArk
One is an enterprise identity platform. The other is running in production in 10 minutes.
These operate at completely different layers — one governs who an agent is, the other controls what it can do with email.
| Mailgator | CyberArk | |
|---|---|---|
| Focus | Email access control for AI agents | Enterprise identity and privilege management |
| Email-specific controls | IMAP/SMTP proxy, folder/sender rules | No email proxy, no folder-level rules |
| Setup time | Minutes | Weeks to months |
| Target audience | Dev teams, small to mid-size orgs | Fortune 500 security teams |
| Configuration | Single TOML file, versioned in git | Enterprise admin console |
| Scope | Email only | All identity types (human, machine, AI) |
| Pricing | From €3/mo | Enterprise contracts (custom) |
CyberArk manages identities across your entire organization: human users, service accounts, AI agents, secrets, certificates. If you need to govern all of that in one platform with centralized policy enforcement, CyberArk was built for exactly that scope.
For regulated industries with strict compliance requirements — SOC 2, ISO 27001, FedRAMP — CyberArk has the certifications, audit logs, and reporting that enterprise security teams expect. These aren't things you bolt on after the fact.
If your company already runs CyberArk for PAM (Privileged Access Management), extending it to cover AI agent identities means one less vendor. The investment is already made — using it more broadly makes sense.
CyberArk manages who an AI agent is. Mailgator controls what it can do with email. CyberArk can grant or revoke access to a mailbox — but once access is granted, it's all-or-nothing. Mailgator can say "read Invoices, but not HR, and get approval before sending." These are different layers and both matter.
Download the binary. Write a TOML config. Start the proxy. CyberArk requires procurement cycles, professional services engagements, and multi-week integration projects. Mailgator is production-ready before your first CyberArk scoping call ends.
CyberArk is priced for enterprise — think hundreds of thousands per year. Mailgator starts at €3/mo. If you have 5 engineers and 3 mailboxes, you don't need a six-figure security platform to secure your agent's email access.
Rules live in a TOML file. Version it in git, review changes in PRs, deploy with your existing CI/CD pipeline. No clicking through an admin console, no tickets to your security team, no waiting for policy changes to propagate through a governance system.
CyberArk makes sense if you're a large enterprise that needs unified identity governance across all systems, not just email. If you have a dedicated security team, an active PAM program, and compliance mandates that require enterprise-grade audit trails, CyberArk covers that scope.
Mailgator is for teams that need email access control now, without a multi-month rollout. You can always add CyberArk for broader identity management later — they work at different layers and can coexist. Start with Mailgator, graduate to the full enterprise stack if you need to.
