Push Security Delivers Browser-Native Security as Direct Alternative to SWG and CASB, Targeting the Attacks Proxy-Based Tools Can't See
BOSTON--( BUSINESS WIRE)--Push Security, the most powerful AI-native security tool in the browser, today announced browser-native capabilities that directly address the use cases organizations have traditionally used secure web gateways (SWGs), cloud access security brokers (CASBs) and security service edge (SSE) platforms to solve, including URL blocking, domain categorization, phishing protection, malicious file detection, shadow SaaS discovery and AI usage governance.
"SWGs were designed for a world where the threat was malware crossing the wire, however that world is gone. Today’s attacks play out entirely inside the browser session, long after the network proxy has decided to allow the traffic."
The announcement challenges a market projected to reach $42 billion by 2030, at a moment of growing doubt about its core architecture. Research indicates that gateways and next-generation firewalls miss approximately 60% of malicious web pages, not because of implementation failures, but because of a structural limitation: Network tools see where traffic went, but they cannot see what the user actually saw and did.
“SWGs were designed for a world where the threat was malware crossing the wire, however that world is gone,” said Adam Bateman, CEO of Push Security. “Today’s attacks, like AitM phishing kits, ClickFix lures, session hijacking and OAuth abuse, play out entirely inside the browser session, long after the network proxy has decided to allow the traffic. We built Push to detect and stop attacks at the layer where they actually happen.”
The structural flaw in proxy-based security
Traditional SWG, CASB and SSE architectures intercept and inspect traffic between users and the internet, enforcing URL categorization and policy at the network layer. This requires routing all user traffic through a cloud proxy which introduces latency, creates a single point of failure, and generates friction that consistently surfaces as the top end-user complaint in SWG deployments. More fundamentally, it leaves the browser session itself unmonitored.
Modern credential-harvesting attacks are specifically engineered to defeat the network layer. Adversary-in-the-middle (AitM) phishing kits use infrastructure rotation, trusted CDNs, and bot protection to stay off blocklists. Many now detect when they are executing inside a gateway sandbox environment and disable their malicious behavior during inspection, appearing benign to the network tool, then re-activating when the real user lands on the page.
By the time a phishing domain is categorized, it has typically already been decommissioned. In fact, 89% of phishing domains are active for fewer than two days. Increasingly, adversaries are also abusing trusted services to deliver attacks, bypassing known-bad detections in legacy solutions like network proxies.
Meanwhile, 82% of attack detections are now malware-free, meaning attackers operate entirely within legitimate browser sessions through credential theft, session hijacking and identity abuse generating no network-layer signal for a proxy to act on.
Push recently discovered and blocked ConsentFix, a novel attack technique that takes over Microsoft accounts with no password entry, no MFA prompt and no anomalous sign-in event for network or identity tools to detect. It was invisible to every proxy-based control in the stack. It was only detectable at the browser layer.
Browser-native detection and policy enforcement without breaking traffic
Push operates as a lightweight browser extension deployed to users’ existing browsers, with no traffic rerouting, no proxy infrastructure, and no browser migration required.
Push observes the live browser session from the inside via the rendered DOM, including credential entry events, script behavior, clipboard contents, OAuth consent flows, and file uploads and downloads. Because Push observes client-side network requests from within the browser before encryption, it captures the data that network tools can only access by decrypting and re-encrypting traffic — without the deployment complexity or session-breaking risks of inline TLS interception.
This architecture enables Push to:
Consolidation without disruption
Push does not require organizations to abandon existing network investments to realize value. For security teams looking to consolidate, Push provides a browser-native alternative for the use cases that SWG and CASB deliver imperfectly, at a fraction of the cost of enterprise SSE tiers, which can exceed $375 per user per year . For teams running SSE platforms they intend to keep, Push layers on top, adding behavioral detection, AI visibility and control, and browser extension blocking that proxy-based tools cannot provide by design.
“We’re not asking security teams to do a feature comparison,” said Bateman. “We’re asking them to look at the outcomes they’re actually paying for, and whether a proxy that can't see inside the session is the right tool to deliver them.”
