ChatGPT allowlisting agent with Optimae implementation services
Why Allowlisting Matters
AI agents are becoming a major source of customer discovery, research, and product comparison. If your website blocks or limits AI agents, you lose visibility in AI search results and risk falling behind competitors whose content is accessible to AI systems.
What Makes ChatGPT Agent Safe?
ChatGPT uses cryptographic signatures to prove each request is legitimate.
It’s like a digital passport:
- Impossible to forge
- Automatically verified by CDNs
- Secure by default
When properly allowlisted, ChatGPT becomes:
Safe traffic
A known bot
A verified agent
Allowlisting ensures:
Only verified AI agents get access — not unknown traffic
Every time ChatGPT’s agent communicates with your systems, it uses a secure digital signature — similar to how banks verify transactions. Our team handles the full setup so that every message arriving in your environment is automatically checked and confirmed as coming directly from ChatGPT, ensuring that no impersonation or tampering is possible.
Therefore we follow the following protocol: ChatGPT agent uses the HTTP Message Signatures standard (RFC 9421). Each request includes a Signature and Signature-Input set of headers and a companion Signature-Agent header set to "https://chatgpt.com".
We also implement the safeguards that detect if any message has been altered along the way. If something doesn’t match the verified signature, your system will reject it immediately. You don’t need to understand the technical details — we manage all of that for you. What matters is that your business stays protected from incorrect data, system misuse, or malicious interference.
Ultimately, our role is to ensure the entire process works seamlessly in the background. We install, configure, monitor, and maintain all the security components so your organisation can safely use AI agents without risk.
Our services include:
> Audit on current system
> Strategy
> Bot Management (Akamai, Cloud flare, HUMAN)
> HTTP Message Signatures (RFC 9421)
> ChatGPT Agent Security Documentation
> CDN firewall rules and WAF (Web Application Firewall) basics
> Debugging CDN traffic
> Ongoing support and servoces
In addition, we configure the system to recognise ChatGPT as a trusted, verified source, much like having a verified badge on a corporate account. We set up and maintain the verification keys that allow your systems to automatically confirm every request. If ChatGPT updates its keys, we handle those changes on your behalf.
Allowlisting with Akamai
ChatGPT can safely crawl, read, and summarise your content
Your brand appears correctly in AI search results
Your website maintains full protection and bot security
If your company uses Akamai for security, we simply tell Akamai that ChatGPT is a trusted bot. We do this by adding it to a special “allowed list” inside your security settings. Once added, Akamai will automatically recognise ChatGPT traffic as safe and let it through — you don’t need to do anything. Akamai also handles all the security checks for authenticity on your behalf.
Allowlisting with Cloudflare
If your company runs on Cloudflare, we enable a rule inside Cloudflare that identifies ChatGPT as an approved, verified agent. Once this rule is turned on, Cloudflare will automatically allow all ChatGPT traffic without blocking or challenging it. Cloudflare does all the verification in the background, so no extra setup is needed.
Allowlisting with HUMAN (Sightline / Bot Defender)
If you use HUMAN’s security tools, ChatGPT is already recognised as a trusted AI agent. We simply switch its status to “allowed” inside your bot and traffic settings. HUMAN automatically confirms that requests truly come from ChatGPT and can control what the AI is allowed to do on your site, such as reading pages, logging in, or making purchases.
Allowlisting with HUMAN AgenticTrust
HUMAN’s AgenticTrust system already verifies ChatGPT cryptographically. We can adjust what ChatGPT is permitted to do inside your environment — for example, whether it can browse content, interact with accounts, or perform actions. You decide the level of access, and we configure it safely on your behalf.
Allowlisting with Vercel
If your website is hosted on Vercel, nothing further is required. Vercel automatically recognises ChatGPT as a legitimate and verified agent and allows it to access your site without any changes from your team.
Allowlisting with Other CDNs
If you are using a different content delivery network (CDN), we simply confirm that incoming traffic from ChatGPT includes the correct verification headers. These headers prove the request is genuine. We also check the public key from ChatGPT to confirm the signature is valid — similar to checking a digital ID.
Troubleshooting Tips
If anything goes wrong, the first thing we check is that all the verification headers from ChatGPT are still intact as they pass through your servers or proxies. If a proxy removes or alters these headers, the system may not recognise the agent correctly — and we can fix that quickly.
