What is the main difference between SikkerAPI and AbuseIPDB?

SikkerAPI combines first-party honeypot data with community reports to tell you what an IP actually did (protocols used, commands run, attack patterns). AbuseIPDB is a crowdsourced reporting database that tells you an IP was reported by others.

How do SikkerAPI and AbuseIPDB handle STIX/TAXII?

SikkerAPI includes a native TAXII 2.1 server that any TAXII-compatible client can connect to directly. AbuseIPDB does not have a native TAXII server, but has OpenCTI connectors that convert its JSON API responses into STIX format for import into OpenCTI.

Can I use SikkerAPI and AbuseIPDB together?

Yes. Using both provides two independent data sources for maximum coverage. SikkerAPI combines its own honeypot observations with its community reports, while AbuseIPDB draws from a separate, larger reporter community.

How does SikkerAPI pricing compare to AbuseIPDB?

SikkerAPI starts at $7/month for 7,000 daily lookups. AbuseIPDB starts at $19/month for 10,000 daily lookups. Both offer free tiers with 1,000 lookups/day. SikkerAPI includes all features (blacklist filtering, TAXII, bulk check) on every tier including free.
