The Top 10 Alternatives To Zscaler (2026)

• Detects and blocks adversary-in-the-middle phishing in the browser, so a page that passes reputation checks is still stopped if it starts harvesting credentials
• Inventories every app and local account in use, including shadow SaaS and AI that were never routed through a proxy
• Allows you to apply data controls to uploads, downloads, and clipboard activity in the browser, with regular expression matching for secrets and PII
• Detects authentication paths that bypass SSO, and provides identity hardening reports on password reuse and missing MFA
• Forwards structured events to Sentinel, Splunk Cloud, Datadog, Panther, and Cribl Cloud alongside existing gateway logs

Push Security isn’t a like-for-like replacement for Zscaler because it isn’t a gateway or zero trust network access (ZTNA) tool; it doesn’t offer private application access, cover non-browser traffic, or offer network-layer inspection. However, we think Push is a strong solution to pair alongside a gateway for teams finding that their existing solution is leaving identity and SaaS blind spots, or as a standalone tool in organizations where BYOD and contractor devices can’t be steered through a proxy at all.

• Malware detection and sandboxing use Check Point’s threat emulation to catch zero-day threats, ransomware, and phishing before they land
• Endpoint agent runs quietly in the background, giving security teams full visibility without disrupting users
• Policy enforcement works across remote and office-based employees from one console, with automated response and recovery features
• GenAI Protect controls extend security governance to generative AI tool usage

We think Check Point Harmony works best for organizations that want consolidated web, endpoint, and email protection without having to manage multiple vendors. Teams already in the Check Point ecosystem will get the most from the tight product integration. If your threat model prioritizes advanced malware prevention and you value single-pane management, this covers a lot of ground.

• DNS-layer filtering blocks malicious domains before a connection is established, and can be bought on its own as a first step into SSE
• AI Access discovers the third-party generative AI tools employees are using and applies access and data controls to them
• Experience Insights, powered by ThousandEyes, traces the user’s path to an application, so support teams can tell whether a slowness complaint is the device, the network, or the security service
• Talos threat intelligence feeds detections, Duo supplies the identity signals behind access decisions, and Meraki SD-WAN integration covers branch traffic

We think Cisco Secure Access makes most sense for organizations already running Cisco networking or Duo that want web, SaaS, and private application access under one console, rather than stitched across multiple vendors. Licensing is usually per user, though bandwidth-based site licensing is available if you run Cisco SD-WAN. In terms of adoption, the DNS-first entry point is the quickest way in; you can start by pointing DNS forwarders at Cisco’s resolvers, then add proxy inspection and private application access later, which is a gentler adoption curve than committing to a full proxy rollout on day one.

If you’re currently a Cisco Umbrella customer, your license won’t carry over to Secure Access like-for-like, so you’ll need to map your current capabilities onto the Secure Access packages before renewing. That said, Cisco says its automated tool typically moves an Umbrella tenant across in under an hour, and reviewers who have made the jump describe the upgrade path as straightforward.

• Global network keeps DNS filtering and threat protection low-latency across locations
• Policy building is straightforward for core use cases: DNS filtering, granular security categories, and phishing and ransomware blocking
• AI security controls let teams block unauthorized AI applications and restrict data uploads
• First SASE platform to support post-quantum encryption across its entire stack as of February 2026, covering SWG, ZTNA, and WAN traffic
• Remote browser isolation available as an add-on for high-risk browsing

We think Cloudflare Gateway is a natural fit for two audiences: SMBs that want free or low-cost SWG protection, and larger organizations already running Cloudflare infrastructure. If you need a performance-first gateway with strong DNS filtering and a path to full Zero Trust, this is well worth evaluating. Teams needing advanced security controls should budget for higher tiers where those capabilities unlock.

• Over 190 pre-built data security policies apply across cloud and endpoint devices, which are particularly helpful for achieving compliance
• User entity behavior analytics (UEBA) capabilities track user behavior across endpoint, email, network, and cloud channels
• SWG protects against phishing pages, unsafe downloads, and compromised sites, covering mobile and desktop users
• Over 300 points of presence worldwide with 99.99% verified uptime since 2015

We think Forcepoint ONE SWG works best for organizations prioritizing data protection and compliance, not just threat blocking. If you need pre-built DLP policies across multiple channels with insider threat monitoring, this covers a lot of ground. Smaller teams should factor in the setup complexity and plan for dedicated onboarding resources to get full value.

• FortiGuard URL Filtering Service uses AI-driven behavior analysis to block unknown malicious URLs with near-zero false negatives
• Database covers over 307 million categorized URLs across 90+ categories, including categories for artificial intelligence and cryptocurrency sites
• SSL inspection provides deep visibility into encrypted traffic, including TLS 1.3
• Real-time threat feeds block known malware and phishing sites, with reporting across network and web security layers from one dashboard

We think FortiGate Web Filter is best suited for organizations already invested in the Fortinet ecosystem that want integrated network and web security from a single vendor. The threat intelligence provided by FortiGuard is strong, and the consolidated management simplifies operations. Teams looking for a cloud-native SWG or those without existing Fortinet infrastructure should consider whether the appliance-based model fits their deployment needs.

• Adaptive Clientless Rendering (ACR) technology uses DOM mirroring to transmit clean, lightweight web content to the endpoint
• Bundles SWG, CASB, DLP, proxy, and firewall-as-a-service capabilities in one platform
• URL controls enforce read-only, read/write, or full block policies per site
• Extends governance and threat prevention to autonomous AI agents alongside human users (as of March 2026)
• Deployment works across desktop, laptop, and mobile devices

We think Menlo works best for enterprises that prioritize isolation as their primary web threat prevention model. If your risk profile demands that no active web content reaches endpoints, this delivers on that philosophy with minimal disruption to users. Teams wanting a traditional inspect-and-filter SWG may find the isolation approach more than they need, but for high-risk environments it is a strong choice.

• DLP engine lets admins manage website access, custom apps, and thousands of cloud applications under one framework
• URL filtering uses contextual understanding of content and risk ratings, not just static categories
• Real-time threat protection with AI/ML models detects unknown phishing attacks, malicious files, and HTML smuggling
• Role-based policy customization allows you to set different controls for all user types, from trainees up to directors

We think Netskope fits best if you need a single platform covering web security, cloud app controls, and DLP with deep analytics. If your team runs a hybrid environment and wants consolidated visibility without juggling multiple consoles, this is a strong contender. Plan for dedicated resources during the initial deployment phase to get the most from the platform’s depth.

• SWG layer covers advanced URL filtering, DNS security, malware analysis, user behavioral monitoring, and remote browser isolation
• WildFire threat intelligence pushes continuous updates protecting against emerging threats in real time; sandboxing and AI-powered detection catch zero-day attacks
• Centralized management through Panorama or the Cloud Management Console gives consistent policy enforcement across remote users, branch offices, and headquarters
• March 2026 update to Prisma Access Browser adds protections against shadow AI agents, prompt injection attacks, and agent hijacking

We think Prisma Access is strongest when deployed as part of the full Prisma SASE stack, rather than as a standalone gateway. If your organization already runs Palo Alto Networks firewalls or is building toward a consolidated SASE architecture, this is a natural fit. Teams outside the PANW ecosystem should weigh the onboarding complexity and vendor commitment carefully before signing on.

• SWG delivers URL category-based blocking, application and activity controls, and remote browser isolation for risky sites
• Global threat intelligence platform feeds real-time phishing protection across the stack
• Zero-day malware protection uses adaptive policy enforcement, with granular application visibility and automated incident response
• FedRAMP High Authorization for federal and public sector deployments, with 99.999% uptime through Hyperscale Service Edge

We think Skyhigh fits best if your organization wants a consolidated SSE platform, rather than having to manage separate vendors for SWG, CASB, and DLP. If you already run a multi-vendor stack and only need a standalone web gateway, the broader platform may be more than you need. The all-in-one approach delivers real operational simplicity for teams ready to consolidate.
