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. Modern email security like Sublime use AI-powered technology to detect and block sophisticated attacks while providing visibility and control over your email environment.
What is the best email security?
The best email security adapts quickly to emerging threats and minimizes false positives. Sublime Security offers an adaptive platform that combines AI-powered protection with unprecedented visibility and control. It detects advanced threats like GenAI-powered phishing attacks and provides comprehensive protection for cloud-based email environments.
What are the main challenges in modern email security?
Modern email security faces challenges from GenAI-powered spear phishing campaigns, cloud-based payload obfuscation, and rapidly evolving attack techniques. 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 or days rather than months, providing more responsive protection against evolving attacks.
What features should I look for in email security?
Look for email security that offer adaptive protection against emerging threats, minimize false positives, provide comprehensive visibility, and include incident response capabilities. The solution should protect against sophisticated phishing, insider threats, and GenAI-powered attacks while offering search capabilities for suspicious messages and actionable threat intelligence.
How does cloud-based email security differ from traditional options?
Cloud-based email security offer greater scalability, faster updates, and better protection against modern threats than traditional options. They provide real-time threat intelligence, automated response capabilities, and protection against cloud-specific threats like obfuscated payloads. Solutions like Sublime are specifically designed to address the unique security challenges of cloud environments.
