Why "good enough" isn’t enough: the case for best-of-breed browser security

Three browser security companies have been acquired by major security platforms in five months. CrowdStrike acquired Seraphic Security in January 2026. Zscaler absorbed SquareX in February. In May, Akamai announced the acquisition of LayerX. Add Palo Alto Networks' earlier acquisition of Talon, and the browser security market has consolidated faster than almost any adjacent security category before it.

These acquisitions recognize that the browser is now where employees work, where AI runs, and where the most damaging attacks on organizations originate. It’s telling that browser security already accounts for 12.6% of the average security budget, and 85% of organizations expect to increase that spend over the next 12-24 months.

But for security buyers, consolidation creates a risk as much as an opportunity. The question isn't whether your existing platform vendor now offers browser security — it's whether what they're offering can actually protect you as the threat landscape evolves.

Why "good enough" isn't good enough in the browser

The consolidation pitch is tempting. If you're already a CrowdStrike, Zscaler, or Palo Alto customer, adding browser security through an existing relationship means fewer vendors, fewer contracts, and a coherent narrative about platform consolidation that plays well internally. 

Security teams make these kinds of tradeoffs all the time — accepting that your SASE vendor's threat intelligence feed may not match a dedicated provider, or that your EDR vendor's vulnerability management module may not match a dedicated scanner — are reasonable decisions where the operational benefit of consolidation outweighs the capability difference.

But browser security is a category where the stakes are too high to accept a "good enough" solution. The majority of all reported breaches now originate in the browser and attacker tradecraft in this space is advancing at an unprecedented rate thanks to AI. These risks warrant the strongest form of defense. Here are three reasons that “good enough” solutions don't give you that:

1. Most platform browser solutions were built for the wrong problems

CrowdStrike's own research puts identity involvement in 80% of all modern breaches. Identity weaknesses played a material role in almost 90% of Unit 42 incident response investigations. The breaches making headlines — 2024's mass Snowflake account compromises, 2025's wave of Salesforce-targeted attacks, and 2026's continued spree of data theft and extortion — all trace back to identity weaknesses exploited through the browser: credentials stuffed into login pages that lacked MFA, session tokens hijacked via AiTM phishing, OAuth consent abused to grant persistent access, and device code flows manipulated to bypass authentication entirely. 

Yet Seraphic was built for browser runtime exploit prevention, SquareX for file-based malware sandboxing, LayerX for access governance and AI usage policy. These are real use cases, but they're not the use cases behind headline breaches. If your browser security solution checks a box for "phishing protection" but can't detect the identity attack techniques that are actually being industrialized and deployed at scale, you have a gap — and the danger is that you don't know it's there.

2. Even solutions claiming the right capabilities often deliver them superficially

Every browser security vendor claims phishing detection, ClickFix protection, and session security. What varies enormously is whether those capabilities work against real, live, never-before-seen attacker infrastructure — or only against known-bad indicators that attackers rotate in minutes. 95% of in-browser attacks detected by Push used bot protection to evade blocklists; 89% of phishing domains are active for fewer than two days. 

A solution that appears comprehensive in a demo or PoV may leave significant gaps when tested against adversaries who understand exactly how security tools work and actively engineer around them. 

3. AI is only going to widen the gap between "good enough" and what you need

When a browser security product is acquired, engineering effort turns inwards towards integration with the parent platform, not advancing detection capability. 

That dynamic plays out differently for each acquisition, but in Seraphic's case it is expected to be particularly heightened. Seraphic works by injecting an agent into the browser's JavaScript runtime. This is the same approach antivirus vendors have used for years, with well-documented stability consequences. Stability is now a top priority for CrowdStrike, which means the Seraphic integration will proceed cautiously. For buyers, that translates directly into slower capability advancement, not faster.

But this is no time for engineering efforts to turn inward, as the threat landscape continues to evolve at an unprecedented rate. You only need to look at the rise of techniques like device code phishing, which have gone from research curiosity to industrialized exploitation in a matter of months — in large part enabled by AI-powered tools and AI-assisted development. Similarly, AI has compressed the time to generate a convincing phishing campaign from hours to minutes. 

But it's not only external threats: 92% of organizations allow employees to use public GenAI applications — every one of them with unsanctioned AI use occurring by design — employees are routinely entering sensitive data into unapproved AI tools, and Gartner predicts 40% of enterprise applications will feature AI agents by end of 2026, up from under 5% in 2025. 

The gap between an acquired product focused on integration and vendors whose single-minded focus is on stopping these emerging threats will continue to widen over time.

How to identify a genuinely best-of-breed solution

Start from your own requirements

Define the outcomes you need before speaking to any vendor. The highest-value browser security use cases are account takeover prevention, advanced phishing detection, identity posture hardening, browser extension security, and shadow SaaS and OAuth governance.

Understand how it detects, not just what it claims

Most solutions rely on IoCs — matching known-bad domains, URLs, and IPs against feeds that attackers rotate in minutes.  There’s a major shortcoming with this approach, though: attackers rotate infrastructure faster than any blocklist updates and use bot protection to stay off threat intelligence feeds, making every attack feel like a zero-day. The only approach that reliably works is TTP-based behavioral detection. Ask every vendor: are you detecting a known-bad indicator or a behavioral technique?

Test against real attacker behavior

Don't evaluate phishing detection with old phishing URLs. By the time you’re running these tests their IoCs will already be on block-lists (see point above). Instead, deploy realistic testing scenarios and look for demonstrable evidence of stopping real-world phishing kits — Evilginx, Tycoon2FA, Sneaky2FA, and so on. 

Assess innovation velocity

Ask every vendor about their research output and feature release history over the past six months — are they discovering and publishing novel attack techniques, or covering what others already documented? Are new detections shipping continuously, or in quarterly cycles? For acquired products specifically, also ask how the roadmap has changed since acquisition. 

Consider operationalization, vendor focus, and lock-in

Many solutions demo well but create significant overhead at scale. Consider whether you want another agent on endpoints, and whether you have the resources to tune granular policies without drowning in false positives. Your requirements might not carry the same weight with a platform vendor with tens of thousands of customers across multiple product lines, versus a dedicated vendor whose entire roadmap exists to solve your problem. And factor in lock-in: every capability consolidated into an existing platform vendor reduces your ability to change direction later.

Why Push is the best-of-breed browser security solution

Think of Push as EDR, but for the browser — high-fidelity telemetry and real-time control across every session, on every device, with no browser migration required. Here’s why customers choose Push as a best-of-breed solution:

Push is built for the security problems that actually cause breaches

The highest-value browser security problems — account takeover prevention, advanced phishing detection, identity posture hardening, browser extension security, shadow SaaS and OAuth governance — all require visibility inside the browser session. Push was built from the ground up for exactly that. The same foundational capability that detects AiTM phishing and ClickFix attacks also surfaces the exposure most security teams don't know they have: across Push's customer base, 1 in 4 logins use passwords rather than SSO, 2 in 5 are unprotected by MFA, and 46.76% of browser extensions carry permissions sufficient to perform account takeover — none of it visible from the endpoint, network, or email layer.

Push detects high-fidelity attacker TTPs, not low-level IoCs

Push's browser extension operates as a flight recorder inside the session, capturing every page load, credential submission, OAuth consent flow, and user action in real time. That telemetry surfaces attacker behavior — the page structure and script signatures of AiTM kits, the clipboard mechanics of ClickFix, the OAuth flow characteristics of ConsentFix — rather than infrastructure indicators that attackers rotate in minutes. This is how Push intercepts “zero-day” phishing using fresh infrastructure and domains every time, while most solutions are stuck playing known-bad whac-a-mole. 

Push’s research and agentic threat hunting keeps you ahead of attacker innovation

Push named ConsentFix and InstallFix before any other vendor detected either in production. That research feeds an agentic detection pipeline built on two learning loops — an inner loop for real-time detection of known techniques, and an outer loop where autonomous agents continuously hunt across 3 million deployed browsers for emerging threats, writing new detections and deploying them to customer environments in minutes. 

Push solves more use cases than just stopping advanced attacks

Push uses the same browser-layer visibility to surface every AI tool, agentic browser, extension, and OAuth integration in use across the organization — and enforce policy on what employees can do inside them in real time, including unsanctioned tools no other layer sees. The same technical capabilities provided by Push also harden the identity attack surface, prevent data loss, accelerate insider investigations, and let security teams write custom detections and policies for organization-specific risks. One extension, one deployment, multiple high-value use cases.

Push is built to be operationalized at scale, not just demoed

Push deploys to 100,000 users in under one hour on a normal workday — no migration overhead or performance impact. The false positive rate is negligible, meaning no alert noise and no policy tuning overhead. And because Push is independent, it integrates into open ecosystems — feeding browser-layer telemetry into your SIEM, XDR, SOAR, and identity tools alongside the rest of your stack, without adding to your platform lock-in.

Final thoughts

Three acquisitions in five months is a strong market signal, but a strong market signal about vendor interest in a category is not the same thing as a strong signal about capability. The attacker techniques and tooling behind breaches in 2026 are evolving faster than any acquired product with split engineering priorities can reasonably track. 

Security buyers who accept a bundled browser solution because it is included in an existing contract are making a procurement decision, not a security decision. The threats in the browser are serious and sophisticated enough to justify the investment in a tool built to stop them. If you agree, Push is worth a serious look.
