Skyhigh Security Alternatives in 2026: The Best Replacement for Skyhigh SWG and SSE

The short answer: if you're looking for a Skyhigh Security alternative in 2026, you want agent-based SSE that runs on the device instead of a cloud proxy carrying twenty years of McAfee Web Gateway heritage. dope.security is the fly-direct replacement most teams shortlist. Skyhigh still works. The question is whether a modern team should keep paying for a proxy architecture, a split codebase, and a roadmap slowed by private-equity debt. For the three-way view, see our Skyhigh Security competitors breakdown.

What Skyhigh Security actually is

Skyhigh Security is the web and cloud security half of the old McAfee Enterprise business. When McAfee Enterprise and FireEye merged and then split, the endpoint side became Trellix and the SSE side became Skyhigh Security. Both sit under the same private-equity ownership.

The core products are Skyhigh Secure Web Gateway (the descendant of McAfee Web Gateway), a CASB with real data-protection depth, and ZTNA, bundled as an SSE platform. The SWG runs the classic model: steer traffic from the user to a Skyhigh cloud point of presence, decrypt TLS, inspect, re-encrypt, forward to the internet. If you want the category background, our explainer on what a next-gen secure web gateway does covers why that proxy detour became the bottleneck.

Skyhigh's data-protection story is genuinely strong. It scored at the top of the "protect data" use case in Gartner's SSE analysis. That heritage is real. So is the architecture underneath it.

Where Skyhigh Security bites in 2026

Three things surface consistently in evaluations.

Split-company dependencies. Skyhigh and Trellix were one company, then two. Skyhigh's SWG still leans on Trellix for advanced sandboxing and threat analysis. That means part of your threat-prevention stack lives on the other side of a corporate divorce, with the integration risk that implies. When two PE-owned companies share history, a codebase, and a debt load, roadmap alignment is not guaranteed.

Legacy proxy architecture. Skyhigh SWG began life as an on-prem appliance, McAfee Web Gateway, and the cloud version inherited that DNA. You get the on-prem product, the cloud product, and the migration guidance to move between FQDNs and PoPs. Every request from every device still hairpins to a Skyhigh data center before it reaches the internet. That's the backhaul tax, and it shows up as latency for anyone not sitting next to a healthy PoP.

Innovation drag. Skyhigh carries a heavy debt burden shared with Trellix, and reviewers repeatedly flag that staffing constraints slow the pace of feature delivery. Customers describe the console as clunky and note that keeping current requires frequent upgrades. When the roadmap moves slowly, the gap between what you need and what ships widens every quarter.

None of this makes Skyhigh a bad product. It makes it a legacy product. The question is whether legacy is what you want to renew.

When Skyhigh Security is still the right answer

Be fair about this. Skyhigh earns its slot when data protection is your single most important requirement and you value its mature CASB and DLP depth above all else. If you have a large security operations team that can absorb console complexity, and you're already invested in the McAfee/Trellix ecosystem, the integration path is real. Highly regulated shops with existing Skyhigh CASB deployments may find the switching cost isn't worth it yet.

Outside those cases, the architecture is worth rechecking.

What a Skyhigh Security alternative looks like

The alternative class that grew in 2026 is agent-based SSE. Instead of routing every connection to a vendor data center for inspection, the agent runs on the device and inspects traffic locally. SSL decryption, URL filtering, DLP, and CASB controls all happen at the endpoint. Traffic flies direct from the laptop to its destination. No cloud proxy in the path.

dope.security is built on this model, delivered through the Fly Direct dope.SWG. What changes when you replace Skyhigh with an agent-based SSE:

One console, one company, one codebase. dope.SWG, Dopamine DLP (endpoint DLP for data in motion, US Patent 12,464,023), CASB Neural (cloud DLP for data at rest), AI-Powered SSPM, and Cloud Application Control all live under dope.console. Nothing depends on a sister company for sandboxing. One roadmap, built from scratch, not stitched together through a merger and a split.

No backhaul. SSL inspection happens on the device, so there's no PoP fleet in the request path. The user in Singapore, the user traveling, the user in a market where proxy SWGs struggle: same enforcement, same speed.

Sub-100 MB footprint. The dope.endpoint agent runs in under 100 MB of RAM and delivers roughly 4x the performance of legacy proxy SWGs. The user doesn't feel the gateway.

Deployment in weeks, not a migration project. Push the agent through your MDM. A Fortune 100 customer deployed 18,000+ devices in record time. Outreach Health secured 99% of devices in one week. There's no FQDN migration guide because there are no PoPs to cut over to.

Skyhigh Security vs. an agent-based SSE: the head-to-head

The AI governance angle

Web filtering is now AI filtering. Your people use ChatGPT, Claude, and Gemini every day. The real question isn't whether to allow them. It's whether you can tell a personal ChatGPT login from an enterprise one, inspect what's in the prompt, and stop sensitive data from leaving the device.

dope.security handles this with a three-layer model. dope.SWG discovers shadow AI use through traffic visibility. Cloud Application Control restricts access to your enterprise tenant only, so personal ChatGPT and Claude logins get blocked at the request layer. Dopamine DLP inspects prompt content in real time and allows, warns, or blocks based on your policy, using zero-retention APIs so content is never stored or used to train a model. That capability ships in the platform, not as a separately negotiated add-on. Our complete guide to AI governance walks through why on-device enforcement is the difference between visibility and control.

Customer evidence

Outreach Health, a healthcare provider with 5,000 to 10,000 employees across 34 offices in Texas, Arizona, and Massachusetts, replaced a legacy SWG and secured 99% of devices in one week. Web access tickets dropped 70% in the first 90 days, and policy changes that used to take days now take minutes. "It's not just great, it's dope. We didn't need a six-page deployment manual anymore," said their security engineer.

Greylock Partners, the Silicon Valley VC firm behind LinkedIn, Discord, Figma, and Workday, replaced a legacy DNS-and-proxy setup with dope.security in 27 days from first proposal to signed contract. The City of Visalia, a California municipality serving 140,000 residents, runs 700+ users on dope.security after perimeter protections stopped following people off-network.

How to evaluate the swap

Pull a real latency benchmark for your geography. Compare a direct connection to one routed through your nearest Skyhigh PoP. The round-trip difference is the backhaul tax.

Add up the three-year TCO honestly: per-user license, migration effort, internal engineering hours, and renewal uplift. Then ask how much of the roadmap you're funding is actually shipping.

Count consoles and count companies. If your threat sandboxing depends on Trellix, your operational risk spans two organizations.

Score AI governance. Can the vendor distinguish personal ChatGPT from enterprise ChatGPT at the tenant layer, and inspect prompt content with a zero-retention guarantee? That's the 2026 bar.

The bottom line

Skyhigh Security is capable cloud-proxy SSE with genuine data-protection heritage, carried by a company working through a debt load and a split codebase. If mature CASB is your one non-negotiable and you're deep in the ecosystem, it can still be the answer. If you're a mid-market or enterprise team that doesn't want to fund a PoP fleet and a shared-debt roadmap to filter web traffic and govern AI, there's a cleaner architecture now, and the architecture is most of the price.
