OverviewLog matches before blockingBlock DDoS participants targeting your regionChallenge a threat actor targeting the finance sectorFilter by attacker countryCombine with attack scoreRate limit threat actors on API paths

Custom rule and rate limiting rule examples using threat intelligence fields. All fields are arrays — use any() with [*].

Caution

Test rules with Log before enforcing. IP-based threat intelligence is a seven-day lookback over shared infrastructure — combine with other signals such as attack score before you block.

Log matches before blocking

Deploy with Log (Enterprise plans) to review matches before enforcing:

Expression:
any(cf.intel.ip.attacker_names[*] != "")

Action:Log

Review matches in Security Events, then change the action to Block or Managed Challenge.

Block DDoS participants targeting your region

Expression:
any(cf.intel.ip.target_countries[*] == "FR") and any(cf.intel.ip.datasets[*] == "ddos")

Action:Block

Challenge a threat actor targeting the finance sector

Expression:
any(cf.intel.ip.target_industries[*] == "Banking & Financial Services") and any(cf.intel.ip.attacker_names[*] == "BLACKBASTA")

Action:Managed Challenge

Filter by attacker country

Expression:
any(cf.intel.ip.attacker_countries[*] == "CN")

Action:Block

Combine with attack score

Block requests flagged by the WAF threat intelligence dataset that also have a low attack score:

Expression:
any(cf.intel.ip.datasets[*] == "waf") and cf.waf.score lt 20

Action:Block

Rate limit threat actors on API paths

Rate limiting rule applying a stricter rate to flagged IPs on your API:

Expression:
any(cf.intel.ip.datasets[*] == "ddos") and starts_with(http.request.uri.path, "/api/")

Action:Block when the rate is exceeded.
