Browser Security Matters in 2025
In the digital workplace, as with anywhere, criminals always go where the valuables are. Today, the vault is no longer just on desktops or local servers. The modern workplace lives inside the browser. Email, SaaS platforms, cloud storage, AI tools, and sensitive files all flow through that single entry point. That’s why cyber attackers now treat the browser as their preferred target. This latest Cyber Insurance News & Information Podcast kicks off Season 2 with Vivek Ramachandran, a cybersecurity veteran and founder of SquareX, a company advancing browser detection and response (BDR). Host Martin Hinton and Vivek explored why browser security has become the frontline of enterprise defense and what individuals and companies can do to build their cyber resilience.

Guest Insights: Vivek Ramachandran on Browser Security
- Shift to Browser-Centric Workflows
- Workers now spend 90% of their time in browsers. Attackers follow the data and identity stored inside them.
- Why EDR Tools Fall Short
- Traditional endpoint detection was built for desktops, not browsers. SquareX brings antivirus-style protection directly inside the browser.
- Common Attacks
- Malicious Extensions: Fake ad blockers or free VPNs steal passwords and tokens.
- Identity Attacks: Single sign-on misuse grants attackers access to cloud storage.
- User Responsibility
- “There is no free lunch,” Ramachandran warned. Free extensions often hide malicious intent. Check publishers, reviews, and install counts before trusting add-ons.
- Attack Frequency
- In companies of 1,000 employees, attackers attempt entry 60,000 times a month. One success can expose the entire network.
- Browser Management
- Few organizations manage browsers properly. Updates and restrictions can block easy exploits, yet many companies leave this step undone.
- Insurance and Compliance Gap
- Cyber insurance policies and compliance frameworks still lag behind browser-focused threats. Risk assessments often overlook this new frontier.
- Future Risks with AI
- AI-driven apps and browsers expand attack surfaces faster than IT teams can respond. Without new layers of protection, criminals will exploit these gaps.
Episode Glossary
The cybersecurity world is filled with acronyms, from BDR to SaaS; here are a few that appear in the episode, along with their definitions.
BDR — Browser Detection & Response
- Why it matters: Most attacks now pivot through the browser and SaaS; BDR gives you in-browser telemetry and control.
- Note: Some teams use BDR to mean “Backup & Disaster Recovery.” Here, we’re using the browser security sense for the episode.
SaaS — Software as a Service
- Why it matters: Your crown-jewel data lives in Google/Microsoft/CRM apps; risk now concentrates in browser sessions, not the LAN.
EDR — Endpoint Detection & Response
- Why it matters: Essential for hosts, but it often can’t see identity theft, token hijacks, or DOM-level tricks inside web apps.
SASE — Secure Access Service Edge
- Why it matters: Network-edge control is great, but it’s blunt against fine-grained user actions within complex SaaS UIs.
SSE — Security Service Edge
- Why it matters: SWG/CASB/ZTNA from the cloud helps, yet still misses in-app behavior unless paired with browser-level signals.
DLP — Data Loss Prevention
- Why it matters: Stops sensitive data leaving—but legacy DLP struggles with AI tools, shadow-SaaS, and copy/paste in browsers.
DOM — Document Object Model
- Why it matters: Attackers abuse live page structures; DOM-aware controls catch overlays, injections, and credential skimmers.
VPN — Virtual Private Network
- Why it matters: Encrypts traffic to the office, but “free VPN” extensions can exfiltrate data, inject scripts, or steal tokens.
SSO — Single Sign-On
- Why it matters: One login opens many doors; reckless OAuth grants let malicious apps read mail, files, or calendars at scale.
MFA — Multi-Factor Authentication
- Why it matters: Still the cheapest way to blunt account takeovers—use phishing-resistant methods (FIDO/WebAuthn) when possible.
SOC — Security Operations Center
- Why it matters: Investigations stall without browser/SaaS logs; SOCs need that evidence to reconstruct modern kill chains.
SIEM — Security Information & Event Management
- Why it matters: Centralizes alerts and logs; add browser/SaaS telemetry, or you’ll miss the first half of many incidents.
CFO — Chief Financial Officer
- Why it matters: Converts cyber risk into dollars (downtime, fraud, lost sales) and decides on budgets, insurance, and risk transfer.
CISO — Chief Information Security Officer
- Why it matters: Owns strategy; increasingly accountable for browser- and SaaS-centric controls and insurability evidence.
AI — Artificial Intelligence
- Why it matters: LLMs/copilots/agents expand attack surface (data sprawl, risky plugins, automated exploits, and prompt abuse).
YOBB — Year Of Browser Bugs
- Why it matters: Signals structural browser risk beyond one-off CVEs; reinforces the need for in-browser monitoring and policy.
Tor — The Onion Router
- Why it matters: Legit privacy tool, but enterprise use can indicate risky browsing or attempts to bypass monitoring.
