Netskope One SSE vs SonicWall Secure Internet Access: Side-by-Side Comparison (2026)

Netskope One SSE

Mid-market and enterprise security teams that need to replace multiple point products with a single policy engine should start with Netskope One SSE, especially if your users are scattered across cloud apps, remote networks, and branch offices. The single-pass inspection architecture eliminates the performance tax of stacking SWG, CASB, and ZTNA separately, and its AI-driven app discovery handles the discovery work most teams skip. Skip this if your organization runs primarily on-premises with minimal cloud adoption or lacks the operational bandwidth to manage centralized policies across five security functions simultaneously.

SonicWall Secure Internet Access

SMB and mid-market teams without dedicated security operations will find real value in SonicWall Secure Internet Access because it handles both internet-facing threats and SaaS sprawl from a single pane of glass, cutting down the alert fatigue that kills small security programs. The tool covers all four NIST CSF 2.0 identity and access control functions while adding continuous monitoring teeth through DNS-layer blocking and device posture checking, which means less manual remediation work. Skip this if you need deep incident response or forensics; SonicWall prioritizes prevention and visibility over post-breach investigation, so teams running mature threat-hunting operations will want something else.
