Metomic vs Netskope: MCP Gateway vs SSE for AI Agent Security

Netskope and Metomic both now claim ground in AI agent security, but they arrive from different starting points. Netskope is one of the largest Security Service Edge (SSE) vendors, a Gartner-recognized leader in the category for four years running, built around Secure Web Gateway, CASB, ZTNA, and inline DLP. Metomic is a purpose-built MCP Gateway. Netskope’s move into MCP-specific security is recent: announced in December 2025 and productized as Agentic Broker within its Netskope One AI Security suite around March 2026. This guide lays out what each platform actually does, so you can weigh a module inside a large SSE platform against a dedicated gateway.

The short version

• Netskope’s foundation is SSE: Secure Web Gateway, CASB, ZTNA, and inline DLP, converged under Netskope One and run over its NewEdge private network.
• Netskope announced dedicated MCP security in December 2025, covering visibility into MCP servers and clients, default-block policy controls, non-human traffic detection, and sensitive-data detection in MCP tool calls.
• That capability was productized as Agentic Broker, part of the Netskope One AI Security suite announced around March 2026, which decodes and secures MCP traffic between agents and enterprise tools and data.
• Metomic is a dedicated MCP Gateway: no agents on endpoints, live in minutes, governing agent traffic through five capabilities, discover, approve, control, redact, and prove.
• Netskope also sells a separate DSPM for SaaS product for data at rest, with documented support for specific apps rather than the full collaboration-tool breadth Metomic covers.

What does Netskope actually do?

Netskope’s core platform is SSE, converging Secure Web Gateway, CASB, ZTNA, and Firewall-as-a-Service under a single product, Netskope One, built on a private global network called NewEdge. Its inline DLP is proxy-based and inspects web, SaaS, and IaaS traffic in real time, with a large library of data identifiers and file-type coverage, a genuine strength for the network and web traffic it was built to watch. Netskope has held a Leader position in Gartner’s Magic Quadrant for Security Service Edge for four consecutive years.

Netskope’s AI-specific work started with SkopeAI, an umbrella for machine-learning techniques applied across the portfolio, and a feature set for visibility and DLP over employee use of known generative-AI web apps like ChatGPT: which apps people use, real-time DLP on prompts and uploads, and risk scoring of AI apps. In December 2025, Netskope went further and announced dedicated Model Context Protocol security: visibility into MCP servers and clients, granular default-block policy controls, non-human traffic detection, event logging, and sensitive-data detection inside MCP tool calls, extending its Cloud Confidence Index risk scoring to MCP servers. That capability now ships as Agentic Broker, part of a broader Netskope One AI Security suite (alongside AI Guardrails, an AI Gateway for internal LLM traffic, and AI red-teaming) announced around March 2026.

For data at rest in SaaS apps, Netskope offers a separate product, DSPM for SaaS, distinct from its inline proxy path. Its own documentation lists supported apps including Salesforce, Box, Microsoft 365 OneDrive, SharePoint, and Google Drive, with stated file-size and per-store scan limits. Slack appears in Netskope’s broader DLP and CASB marketing, but we could not confirm it against the DSPM for SaaS product’s own documented app list, worth checking directly if collaboration-tool coverage is a deciding factor.

What does Metomic’s MCP Gateway do?

Metomic sits directly in the path of MCP-connected agents, wherever your teams use Claude, ChatGPT, Cursor, or another agent calling tools over the Model Context Protocol. It’s hosted and preconfigured, with nothing to install on endpoints, and it governs traffic through five capabilities:

1. Discover. Map every agent, MCP server, copilot, and browser AI tool touching company data, approved or not.
2. Approve. Keep a living registry of the agents and tools your teams are cleared to use, each scoped to least privilege.
3. Control. Decide every request inline, in milliseconds: allow it, redact it, hold it for a person, or block it.
4. Redact. AI Judge weighs what a request actually carries and strips the sensitive part out before it reaches an external model.
5. Prove. Keep a full, streamable record of every agent action, ready for an auditor or a regulator, streamed straight to your SIEM.

Metomic vs Netskope: feature comparison

	Metomic MCP Gateway	Netskope
Core architecture	Purpose-built, standalone MCP Gateway	Security Service Edge platform (SWG, CASB, ZTNA, DLP), with MCP security added as the Agentic Broker module
MCP-specific security	Core product from day one	Agentic Broker, announced Dec 2025, productized within the Netskope One AI Security suite around March 2026
Web/cloud traffic inspection	Not the product’s focus	Core strength; proxy-based inline inspection over the NewEdge network
SaaS data-at-rest scanning	Deep, agentless coverage across Slack, Google Drive, Jira, Confluence, Notion, Microsoft 365, Dropbox, Atlassian, Trello, Salesforce, and more	Separate DSPM for SaaS product, with documented support for specific apps (Salesforce, Box, OneDrive, SharePoint, Google Drive)
Content-aware redaction	AI Judge redacts sensitive content inline before it reaches an external model	Sensitive-data detection within MCP tool calls, per Netskope’s Agentic Broker documentation
Deployment	Hosted, preconfigured, no endpoint agents, live in minutes	Typically deployed as part of a broader Netskope One rollout
Analyst recognition	Not applicable to this comparison	Gartner Magic Quadrant Leader, Security Service Edge, four consecutive years
Audit trail	Full agent-action record streamed to your SIEM	Event logging within Agentic Broker; broader logging across the Netskope One platform
Compliance	SOC 2 Type II (AICPA)	Not covered in this comparison; confirm directly with Netskope

When Netskope is the right choice

Netskope is a strong choice if you’re already running, or planning to run, its SSE platform for web and cloud traffic and want AI-agent and MCP controls to live inside that same operational surface, with one vendor for SWG, CASB, ZTNA, and DLP alongside Agentic Broker. Its scale and analyst track record in SSE are real, established strengths.

When Metomic is the right choice

Metomic is the better fit when you want a dedicated MCP Gateway that deploys independently of a broader SSE platform, live in minutes with no endpoint agents, and when deep, agentless coverage of everyday collaboration tools, Slack, Google Drive, Jira, Confluence, Notion, matters as much as the MCP traffic layer itself. It’s also worth a look if you don’t need, or don’t want to adopt, a full SSE stack just to get agent-traffic governance.

Key takeaways

• Netskope’s foundation is SSE, converging SWG, CASB, ZTNA, and DLP under Netskope One, with real inline proxy strength for web and cloud traffic.
• Netskope’s MCP-specific security, announced December 2025 and productized as Agentic Broker around March 2026, is a newer addition to that platform.
• Netskope’s SaaS data-at-rest coverage runs through a separate DSPM for SaaS product with a documented, narrower app list than Metomic’s collaboration-tool coverage.
• Metomic is a purpose-built MCP Gateway: discover, approve, control, redact, and prove, live in the request path from day one, with no endpoint agents.
• The right choice often comes down to whether you want agent-traffic governance as a module inside a large SSE platform, or as a dedicated, independently deployed gateway.
