Signature APIs

The Netify Agent includes built-in support for automatically updating signatures for applications, categories, and intelligence. If preferred, these signatures can also be managed through in-house orchestration tools or custom build systems.

The Signature API endpoints provide access to the latest application, intelligence, and category mapping files for the Netify DPI engine. We recommend querying the API weekly or monthly to ensure your deployment stays current. For the Intelligence signatures, daily updates are recommended.


Signature Types

The following signature types are used by the Netify DPI engine:

  • Application signatures
  • Intelligence signatures
  • Category mappings for both application and protocols

The location of these signature files depends on the version of the Netify Agent. The following table provides the details.

Version Categories
v5.2.x /etc/netifyd/netify-categories.dat
v5.0.x /etc/netifyd/netify-categories.json
v4.x /etc/netify.d/netify-categories.json

Authentication

To access these endpoints, an API key must be passed in the x-api-key parameter in the request headers. Please contact us for details about acquiring an API key.

Response Codes

The API sends standard HTTP response codes.

Endpoint Summary

The following endpoints provide signature data for the Netify Agent:

Signature API Endpoint
Categories https://agents.netify.ai/api/v2/integrator/signatures/categories
Applications https://agents.netify.ai/api/v2/integrator/signatures/applications
Intelligence https://agents.netify.ai/api/v2/integrator/signatures/intelligence (Version 5.2+ only)

Parameters

version

string
Required. The Netify Agent version used to determine the correct file format and signature patterns. You can specify the full version (e.g. 4.2.5) or a major version number (e.g. 4) to fetch signatures compatible with that major series.

ip_version

integer
Optional. By default, signatures include both IPv4 and IPv6. Set ip_version to 4 to return only IPv4 IPs and network blocks.

Signature Endpoints

GET
https://agents.netify.ai/api/v2/integrator/signatures/categories
Returns category mapping signatures for applications and protocols.
GET
https://agents.netify.ai/api/v2/integrator/signatures/applications
Returns application signatures.
GET
https://agents.netify.ai/api/v2/integrator/signatures/intelligence
Returns intelligence signatures (Netify Agent version 5.2+ only).

Examples

Terminal - Netify
×
# Version 5.0.62 Application Signatures, IPv4 only:
curl -H "x-api-key: {api_key}" \
    --get "https://agents.netify.ai/api/v2/integrator/signatures/applications" \
    --data "version=5.0.62" \
    --data "ip_version=4"

# Version 5.0.62 Category Signatures:
curl -H "x-api-key: {api_key}" \
    --get "https://agents.netify.ai/api/v2/integrator/signatures/categories" \
    --data "version=5.0.62"

The response format is provided in the native format used by the requested version of the Netify Agent. The locations of the signature files are described above.

In addition, the HTTP response headers provide file hash information. The hash should match the raw file format of the downloaded file.

x-sha1-hash: 13e764d0dfe9450964c669a3807cef48193df24d
x-sha256-hash: 15cbc60164586d0d0dd39f6fd133722eef59955dac6b3bb3ffd47018cb892311

In the case of the categories, the hashes for both the categories data and the applications data are provided. These two hashes can be used to ensure that the categories and application signatures are from the same dataset.
