The short version

  • Each has a real cost: Legit Security pricing requires contacting sales, making cost comparison difficult; Proofpoint licensing is per user per year with each capability as a separate stock item, so the platform shown in a proof of concept is normally several products, and adding awareness training, data loss prevention or insider threat monitoring later is a fresh negotiation rather than enabling a feature.
  • They diverge on capability: Legit Security covers VibeGuard AI code scanning, Proofpoint covers Inline secure email gateway.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Legit Security

  • Pricing requires contacting sales, making cost comparison difficult
  • No published pricing tiers or free tier available
  • Requires integration with existing SAST and SCA tools for full capability
  • Focused primarily on code security within development lifecycle
  • Newer entrant with less market presence than established competitors

Proofpoint

  • Licensing is per user per year with each capability as a separate stock item, so the platform shown in a proof of concept is normally several products, and adding awareness training, data loss prevention or insider threat monitoring later is a fresh negotiation rather than enabling a feature.
  • It sits inline with MX records pointed at it, so any service degradation is a mail outage for the entire organisation, and both migrating on and migrating off are cutovers with queueing, rollback planning and a real risk of message loss.
  • Most customers on Microsoft 365 E5 or Google Workspace Enterprise are already paying for native filtering, so Proofpoint is a second licence layered over a capability the organisation owns, and that comparison is raised by finance at every single renewal.
  • The administration console carries a decade of acquisitions: the classic gateway policy routes and filters do not share a model with the newer module interfaces, rule evaluation is order-sensitive in ways that surprise untrained administrators, and mistakes there silently change what is delivered.
  • Quarantine management is a standing helpdesk workload because legitimate bulk mail, invoices and supplier notifications are held, and unless end-user digests are configured and users are taught to use them, the security team becomes the mail release desk.

Answered from the vendors’ own pages

Legit Security: What is VibeGuard and how does it work?

VibeGuard is Legit Security's core feature that scans AI-generated code directly within IDEs like GitHub Copilot and Cursor, identifying vulnerabilities before code leaves the developer's editor.

Source
Proofpoint: Does it replace Microsoft Defender for Office 365?

Functionally it overlaps heavily, and running both means paying twice for filtering. Most Proofpoint customers on Microsoft 365 keep Defender licensed because it is bundled in E5 and use Proofpoint as the inline gateway. Expect to justify that duplication annually.

Legit Security: What AI code assistants does Legit Security support?

Legit Security integrates with GitHub Copilot, Cursor, and Claude to scan AI-generated code for vulnerabilities.

Source
Proofpoint: Who owns Proofpoint?

Thoma Bravo, a private equity firm, which took the company private in 2021. It has continued to acquire since, including Tessian, Normalyze and Hornetsecurity, which is why the portfolio spans so many adjacent categories.

Legit Security: How does Legit Security's AI remediation feature work?

The platform uses AI to suggest specific code fixes for identified vulnerabilities and can automatically create tickets in Jira with full context for developers to review and apply.

Source
Proofpoint: Do I have to change my MX records?

For the gateway, yes. That is what makes it inline and able to block before delivery. Some newer capabilities integrate through the mailbox API instead, but the core protection model is MX-level.

Legit Security: Does Legit Security support compliance reporting?

Yes, Legit Security automates compliance automation with SBOM generation and can generate compliance reports for security and regulatory requirements.

Source
Proofpoint: Is security awareness training included?

No, it is a separate subscription. It integrates well with the threat data, so training can target the users actually being attacked, but it is a distinct line item on the quote.

Proofpoint: What does Threat Response Auto-Pull actually do?

It removes messages from mailboxes after delivery when the verdict changes, including copies that users forwarded internally. It is the answer to the case where a link was clean at delivery and weaponised an hour later.
