Comparison
CitrusGlaze vs Perimeter 81
Perimeter 81 (now Check Point Harmony SASE) does cloud-based ZTNA with network DLP. CitrusGlaze does prompt-level DLP — catching the secrets, injections, and tool calls that network-level inspection misses.
| Feature | CitrusGlaze | Perimeter 81 |
|---|---|---|
| Focus | AI traffic security | Cloud ZTNA + SWG + CASB (general network security) |
| Data processing | Local-first — AI traffic inspected on your device | Cloud-routed (traffic through Check Point cloud) |
| Approach | Local prompt firewall (network layer) | Cloud SWG + agent-based ZTNA |
| AI tool coverage | 39+ verified (CLI, SDK, agents, browser) | Browser + managed apps (limited CLI/agent visibility) |
| Secret detection | 349+ AI-specific patterns (real-time blocking) | Network DLP + ThreatCloud AI signatures |
| Injection detection | 18 pattern groups + heuristics | Not a focus (network threat prevention) |
| Cost tracking | Per-request token counting + cost attribution | Not available |
| Deploy time | 5 minutes | Hours to days (cloud agent + network config) |
| Price | Free + enterprise pricing | $8-12/user/month basic, enterprise custom |
| Source code | Scanner is open source (MIT) | Proprietary / closed source |

Key differences
Prompt-level DLP vs network-level DLP
Perimeter 81's DLP operates at the network level — it can identify sensitive data patterns in HTTP traffic, but it doesn't understand the structure of AI prompts, tool calls, or model responses. CitrusGlaze provides prompt-level DLP: 349+ patterns specifically tuned for what developers paste into AI prompts (API keys, database credentials, internal URLs, proprietary code). The difference matters because an AWS key embedded in a 50-line code block inside a prompt looks nothing like a file upload — network DLP misses it, prompt-level DLP catches it.
AI-specific vs general-purpose security
Check Point added AI security features to Perimeter 81 through their ThreatCloud AI platform, but it's fundamentally a network security tool with AI awareness bolted on. CitrusGlaze is purpose-built for AI traffic: prompt injection detection (18 pattern groups), Cedar policy engine for tool governance, loop detection for runaway agents, honey token exfiltration alerts, and cost tracking. These aren't features you can add to a ZTNA product — they require understanding AI-specific traffic patterns at the prompt level.
Local-first vs cloud-routed
Perimeter 81 routes traffic through Check Point's cloud infrastructure for inspection. This works for web browsing and SaaS access, but it means your AI prompts — which often contain proprietary code, internal documentation, and API credentials — travel through a third-party cloud. CitrusGlaze inspects AI traffic locally on each machine. Your sensitive data is scanned on your device before it reaches the AI provider, and it never passes through our infrastructure.
Transparent detection vs black-box intelligence
Perimeter 81 leverages ThreatCloud AI — a powerful but opaque threat intelligence engine. When it flags something, you get an alert with a threat category. CitrusGlaze shows you exactly which of the 349+ patterns matched, which stage of the 9-stage pipeline caught it, and the specific content that triggered the detection. Every policy is a readable Cedar rule you can audit and modify. For security teams that need to explain decisions to developers, transparency matters.
Honest assessment
Perimeter 81 was acquired by Check Point for ~$490M and is now part of the Harmony SASE suite. That gives it access to Check Point's decades of threat intelligence, enterprise support infrastructure, and existing customer relationships. If you're already a Check Point shop or need a full ZTNA/SWG/CASB stack, Perimeter 81 integrates naturally.
CitrusGlaze is laser-focused on AI traffic security. We don't replace your VPN or provide zero-trust network access. What we do is catch the things network security tools miss: secrets embedded in prompts, prompt injection attacks, tool call governance, agent loop detection, and AI cost attribution. These are prompt-level problems that require prompt-level inspection.
Perimeter 81 starts at $8-12/user/month. CitrusGlaze is free for developers, with enterprise pricing on request. The decision comes down to what you're solving: general network security with some AI awareness (Perimeter 81), or deep AI-specific security (CitrusGlaze). Many teams run both.
