Is the Browser Becoming the New Endpoint?

The debate over whether the browser is the new endpoint is evolving, but it’s clear that its use has surged and security must catch up. The workday now revolves around the browser, which holds highly sensitive data such as credentials and session information as employees access web and cloud apps, join meetings, and conduct research. Threat actors are already conducting browser attacks through vulnerability exploitation or malicious extensions, with attacks often lacking malware, which makes detection harder.

High-profile incidents, including a Snowflake attack last year that affected downstream database customers, underscored the third‑party risks and the need for stronger browser security. The piece notes that attackers can leverage stolen credentials and social engineering to harvest data for phishing and eventual breach, arguing that the browser is a focal point for both risk and defence.

Security teams are shifting toward isolating browser activity from endpoints and integrating browser protections with network security, including SASE, to achieve broader threat prevention without overburdening teams.
