Work moved to the browser. Most security controls didn't follow it there.

Business applications have largely moved to SaaS, and staff now reach them through a browser. Credentials are entered there, files move through there, and with generative AI, more and more sensitive information passes through a text box in a browser tab.

The rest of the security stack was built to watch somewhere else: the inbox, the device, the network, the sign-in. Attacks that slip past email and past the user tend to land in the session between them, where most controls lose sight.

This report looks at that layer: what browser security can see and stop inside the session, how it sits alongside the controls you already run, and where it can replace a VPN. We assessed each product on its architecture first, because that sets what it can see.

The browser is the primary work surface for Australian organisations, yet most security controls have zero visibility.

The average Okta customer now runs 101 apps1 and staff access those apps through the browser, in sessions outside the view of security.

In FY2024-25, ASD responded to 11% more cyber incidents, and the average self-reported cost of a business cybercrime report rose 50% to $80,850.2

When the IT team locks down AI tools or restricts SaaS access overnight without guidance, staff route around it, moving to personal devices, personal accounts, or personal subscriptions.

From session data
to sold on the dark web

The browser is where attackers steal credentials and active session tokens. The dark web is where they profit.

Attackers buy adversary-in-the-middle phishing kits3 to steal valid tokens. Once an attacker holds a valid session token, they inherit all that user's access without triggering any further authentication challenge.

In practice

In April 2026, Vercel disclosed a breach that began at Context.ai, a third party AI tool one of its staff had trialled. A Context.ai employee’s computer was infected with the Lumma infostealer. Context.ai says an attacker then reached its AWS environment and likely took OAuth tokens. One belonged to a Vercel employee who had signed up with a corporate Google account and granted “Allow All” access. The attacker used it to take over the account and move into Vercel’s systems. Nobody broke through Vercel’s perimeter.4

AI is reshaping what "trust the browser" means

Enabling staff with AI is now urgent, and most organisations are already behind it: three in four workers in Australia and New Zealand now actively use AI apps, up from 53% a year earlier.5

Attackers exploit that gap by cloning popular AI assistant extensions: in January 2026, two fake AI sidebar extensions were found stealing ChatGPT and DeepSeek chats from about 900,000 users. Some legitimate extensions have added similar collection as a product feature: Secure Annex found the Similarweb extension began capturing AI prompts and responses after a May 2025 update.6 Detection means watching extension behaviour over time, not just at install.

Agentic browsers, the kind that take actions on a user's behalf, read untrusted webpage content as if it were a user instruction. A staff member asks the agent to summarise a Reddit thread. Hidden text in a comment tells it to collect the user’s email address and a one-time login code from Gmail and post them back to Reddit, handing the attacker the account. There is no phishing click and no malware, just the user’s own signed-in session doing the attacker’s work.7

Browser security stays in the session, which makes it the reliable control when productivity and exposure pull in different directions. It's the layer that enables staff productivity, while giving leadership the confidence that staff are using those tools correctly.

Security Outcomes

With the threat context as a backdrop, what do information technology professionals prioritise when considering a browser security solution?

  • Frank De Pasquale, Chief Executive Officer at Tekspace
  • Stacy Gurrie, Chief Executive Officer at Byte
  • Mathew Jose, Chief Information Security Officer at CodeBlue NZ

What matters in your assessment? Whatever the domain, a security product earns its place against the same four outcomes. Choose each to see how we assess the browser security category.

Stops threats inside the browser session, including risky AI and SaaS use.

  • Intervention inside the browser session itself, not at the network edge
  • Credential theft, malicious extensions and zero-day web content stopped in place
  • Generative AI and unsanctioned SaaS use governed at the point of interaction

Product Landscape

Comparing browser security products is complex. Solutions overlap and differ in approach; browser extensions, enterprise browsers and cloud-hosted isolation platforms. Tekspace's Cyber Continuum™ ranks 13 of the best browser security products in one transparent, measurable spectrum.

Category Findings

Browser security is an architectural shift, and your last line of defence when every other control has failed.

Many of the corporate breaches we assess could have been stopped at the browser. Its most valuable capability is what no other layer offers: visibility inside the session. That is what tells an approved tool apart from sensitive data being pasted into a personal account, letting teams unlock productivity without adding exposure.

Where it sits in your stack

Email security judges the message, EDR watches the device, and identity checks the person at sign-in, then issues a session token that carries their access from there. SSE and SASE platforms inspect traffic in transit, and some now add browser controls on top. The session sits between all of them, and browser security is the control placed inside it. With zero trust network access it can also retire VPN, VDI and DNS point solutions, which in our experience is the most overlooked capability in the category.

Architecture sets the ceiling. A browser extension on its own cannot see traffic at the DNS level, which rules out true zero trust network access. Check that rules still hold when someone switches browser or opens a private window, and whether sensitive data can be stripped from a prompt before it leaves the browser.

Where to start

Most organisations arrive with a narrower problem: where staff can go, intellectual property leaving, or an incident that ended in the browser. Start there.

  1. Write down the problem, and how you will know it is solved.
  2. Map the business systems staff use in the browser and the data each one holds.
  3. Run a shortlisted product in monitor-only mode with ten to twenty everyday users, so you see your own data before you set policy.
  4. Apply controls where the risk sits, one group at a time.

Several specialists in this report now sit inside larger security platforms, so if you already run one, test how deep its browser layer goes. Match the architecture to your risk; you may not need every capability on day one. We hope this research helps you make a deliberate, not reactive, choice.

Browser Security category

What this report does and doesn’t claim to cover, how we compare products fairly, and what to do if you still have questions.

Scope

This report evaluates browser-native edge security platforms delivering web threat prevention, browser-based data loss protection, SaaS access governance, and GenAI usage controls. It does not cover traditional network security products (SASE, SD-WAN, secure web gateways operating at the network layer), standalone endpoint detection and response platforms, or broader governance/risk/compliance tools.

Feature Granularity Model

We compare products at what we call Level 2: The Functional Group: specific enough to be meaningful, broad enough to compare very different products fairly, without losing sight of how they’re meaningfully different.

Further questions

Why isn't a secure web gateway, CASB, or the browser's own built-in protection enough on its own?

Built-in browser protections, secure web gateways and CASBs are all built to catch known-bad sites and traffic in transit, not to see inside a session after a user has already authenticated. As this report's threat context shows, most initial access today arrives without malware at all, using stolen credentials and hijacked session tokens that those tools were never designed to catch, which is why a dedicated browser-layer control exists.

How is this different from a traditional secure web gateway (SWG)?

A traditional SWG sits at the network layer, routing traffic through a gateway to catch known-bad destinations, which leaves it blind to what happens inside an authenticated SaaS or GenAI session running in the tab. The platforms in this report operate at the browser and DNS layer instead, giving them visibility into that session activity a network-layer gateway cannot see, along with genuine Zero Trust Network Access rather than a bolt-on VPN replacement.

How were the 13 vendors in this report actually compared?

We normalised the market down to 40 scored features and assessed each vendor at what we call the Functional Group level: specific enough to be meaningful, broad enough to compare very different products fairly. See Feature Granularity Model above for how that scale works.

Two of these vendors have been acquired since publication. Does that change the findings?

Seraphic was acquired by CrowdStrike and is now sold as Falcon Seraphic Enterprise Browser. LayerX was acquired by Akamai and still sells under its own name. Both were assessed as standalone products and neither has been reassessed since. What changes is how you buy them, not what they were found to do. Where a product has been folded into a larger platform, check the packaging and commercial terms before comparing it against a standalone tool.

What happens if I want another vendor assessed?

Get in touch. This report focuses on solutions widely regarded as market leaders or strong emerging players, not every product on the market, and we are glad to look at ones we have not yet covered.
