How the Blue Coat Modernization Program Works

The Blue Coat Modernization Program is a Skyhigh Security offer that offsets the cost of moving off Symantec Edge Secure Web Gateway (formerly Blue Coat ProxySG and ASG) to Skyhigh Hybrid SSE Mesh, paired with a guided migration. Skyhigh SWG deploys on-prem, hybrid, or in the cloud, so an existing on-prem ProxySG deployment can be replaced without a forced move to the cloud.

Leaving a Secure Web Gateway is usually stalled by two fears — cost and disruption. The Blue Coat Modernization Program removes both when you move off Broadcom (formerly Symantec/Blue Coat) ProxySG, Advanced Secure Gateway (ASG), and Edge SWG to Skyhigh Hybrid SSE Mesh.

Who the program is for

It is aimed at teams running Blue Coat, Symantec or Broadcom web-security appliances who are hitting one of three triggers.

• End-of-life pressure — an SGOS version or appliance model that is at, or approaching, end of life (see the end-of-life and migration guide for exact dates).
• Renewal or licensing friction — rising maintenance costs or complicated renewal terms under Broadcom.
• A forced tooling change — the move to SGOS 7.4 removes the legacy Java console and policy manager, so staying put still means re-learning how you manage policy.

At the same time, autonomous AI agents operating inside enterprise networks over persistent WebSocket connections are creating a zero trust gap that conventional cloud proxy inspection cannot reach. Addressing that gap requires local enforcement at the network edge.

What the program includes

A financial offset, deployment flexibility, and a path to full SSE without adding another console.

• A financial incentive that offsets the cost of leaving your existing Blue Coat investment, so the economics aren’t the barrier — an advisor sizes the specifics for your estate and timing.
• Deployment flexibility — replace ProxySG on-prem with local control where compliance, sovereignty, or OT/SCADA requirements demand it, run hybrid during transition, or move to cloud — on your schedule.
• A path to full SSE — the same platform extends to CASB, DLP, ZTNA, Secure Browser Controls, DSPM, RBI, and the AI Security Platform: Unified Data Protection Across Every Channel when you’re ready, without adding another console.

Why now

The timing is driven by Broadcom’s own lifecycle, and by the fact that the policy-rework cost lands whether you stay or switch.

Broadcom announced SGOS 7.3 end of life on December 31, 2024, giving customers two years from that date to move to SGOS 7.4; SGOS 6.7 has been end of life since December 2023. You can confirm your version and model against Broadcom’s product lifecycle article. Upgrading to SGOS 7.4 to stay supported also removes the Java Management Console and Visual Policy Manager — so the policy-rework cost exists whether you stay on Blue Coat or switch. The end-of-life and migration guide walks through both paths.

What you’re moving to

Skyhigh Hybrid SSE Mesh — a converged platform that keeps the data plane on premises where you need it and extends to cloud when you’re ready.

Skyhigh Hybrid SSE Mesh is ranked #1 in the Advanced SSE Use Case in the 2026 Gartner® Critical Capabilities for Security Service Edge, trusted by more than 3,000 organizations including 80 percent of the largest global banks and nearly half of the Fortune 100, delivering 99.999% uptime and protecting 20+ million users, with integrated Remote Browser Isolation at no extra cost, agentless Secure Browser Controls with inline AI prompt inspection and WebSocket-aware coverage at the local network edge, an integrated CASB registry, and an industry-leading DLP engine. It adds Modern AI Threat Detection with inline emulation-based sandboxing and UEBA, and AI Security governing AI tool access, blocking high-risk AI engines, and enforcing managed-device-only policies. For teams that want to keep on-prem control today while opening a cloud path, Secure Web Gateway for Hybrid extends on-prem policy to the cloud in a single action, and the broader Security Service Edge platform converges SWG, CASB, ZTNA, DLP, DSPM, Secure Browser Controls, and RBI on one console.

How the migration works

Switching is a guided, phased process designed to avoid a big-bang change — and it is backed by Skyhigh services rather than left to your team alone.

Discovery and assessment come first, then policy re-implementation using your existing CPL library as the blueprint, then a pilot or parallel run, then a staged cutover. Comparing vendors before you commit? See what to require in a Blue Coat alternative and the ProxySG end-of-life guide.
