BackWhat is Traffic Light Protocol (TLP) in threat intelligence?
Traffic Light Protocol (TLP) in threat intelligence is a standardized marking system that tells recipients how far cyber threat information can be shared.
In traffic light protocol threat intelligence workflows, TLP helps teams exchange useful intelligence without exposing sources, victims, investigative details, or remediation plans to the wrong audience.
How does it work?
An information owner applies a TLP label before sending a report, indicator, advisory, or incident update. Recipients use that label to decide who may see it and whether redistribution is allowed.
traffic light protocol threat intelligence is most useful when everyone treats TLP labels as instructions, not suggestions. The source should clarify edge cases before recipients forward the information.
| TLP label | Sharing boundary |
| TLP:RED | Do not share beyond named recipients; use for highly sensitive information requiring direct handling. |
| TLP:AMBER | Share only with people who need it to reduce risk within the recipient organization or its clients. |
| TLP:GREEN | Share within the wider security community, but not publicly. |
| TLP:CLEAR | Share without restriction, subject to normal copyright and disclosure rules. |
Traffic Light Protocol vs data classification
TLP is not the same as a corporate data classification scheme. Data classification describes business sensitivity; TLP describes how recipients may redistribute specific threat information.
A TLP:CLEAR indicator can still describe a serious threat, while TLP:RED information may be sensitive because it reveals a victim, source, investigation, or planned response.
How Hexnode supports Traffic Light Protocol
Hexnode supports the endpoint action side of traffic light protocol threat intelligence. When TLP-labeled information recommends device-level action, Hexnode UEM helps authorized teams use endpoint visibility, policy enforcement, compliance checks, patch workflows, application controls, and remote actions to validate exposure and apply remediation.
This keeps handling and response separate: TLP governs who can see the intelligence, while Hexnode helps approved teams act on it consistently across managed endpoints.
When should organizations use it?
Organizations should use TLP when sharing intelligence with ISACs, vendors, MSSPs, incident responders, regulators, or internal groups that do not all need the same level of detail.
It is especially useful for active incidents, vulnerability coordination, malware analysis, leaked data investigations, and reports containing indicators, exploit details, infrastructure, or affected-party information.
FAQs
No. TLP controls redistribution; severity should be handled with a separate risk, priority, or incident rating.
It limits sharing to the recipient organization only, making it useful when client-level redistribution would expose sensitive incident details.
Yes. The originator can relax or tighten the label, but recipients should ask before broader sharing.
