Value proposition

Delivers military-grade security (zero-day protection, anti-phishing) across any existing browser without requiring a proprietary 'secure browser' or impacting the native user experience.

Products and solutions

["Seraphic Browser Runtime Security (Exploit prevention)","AI Agent Security (Governance and protection for AI interactions)","Enterprise Data Loss Prevention (DLP) for Web","Anti-Phishing and Credential Protection","Governance and Compliance Dashboard"]

Unique value

Unlike competitors that require users to switch to a proprietary 'secure browser,' Seraphic operates as a lightweight security layer within existing browsers (Chrome, Edge, Safari), maintaining full functionality while stopping exploits at the runtime level.

Target customer

Global enterprises, financial institutions, healthcare organizations, and companies utilizing AI agents or managing remote/hybrid workforces.

Industries served

["Cybersecurity","Financial Services","Healthcare","Technology","Government & Defense"]

Technology advantage

Utilizes a proprietary engine that prevents zero-day exploits and memory-based attacks before they can execute. Its recent pivot into 'AI Agent Security' allows it to monitor and secure the data flow between employees and LLMs, preventing prompt injection and sensitive data leakage.

How they differentiate

Unlike competitors that require a proprietary 'secure browser' (like Island or Talon), Seraphic provides a browser-agnostic security layer that works across any existing browser (Chrome, Edge, Safari). It focuses on runtime exploit prevention and has recently pioneered security for AI agents and LLM interactions.
