Frequently asked questions

What is email security?

Email security refers to protective measures that prevent unauthorized access to email accounts and protect against threats like phishing, malware, and data breaches.

Traditional solutions struggle to keep pace with these threats. Advanced email security platforms must adapt quickly, reduce false positives, and provide comprehensive visibility to address these evolving challenges.

How does AI improve email security?

AI enhances email security by detecting sophisticated phishing attempts that evade traditional defenses. It extracts detection signals, generates potential coverage, and backtests through layers of protection. AI-powered platforms like Sublime can adapt to new threats in hours, not months, providing more responsive protection against evolving attacks.
