Transaction edges get mapped
Probes can show which trading, payment, data, and remote access interfaces are reachable.

The coverage
What our sensors observed
Our sensors saw probes against trading interfaces, market data services, payment systems, remote access, and databases. The mapping covers transaction services and the supporting systems teams use to operate them.
Why use this feed
Trading gateways, market data, payment services, and remote administration do not all accept the same callers. Review the feed at each exposed boundary alongside counterparty allowlists and existing access rules. This gives the firewall a current set of observed scanner sources without changing who is authorized to connect. Check required data subscribers and maintenance networks before enforcing a block on a service that must stay available.
The challenges
Scanning can reveal a reachable service before an exploit attempt, whether a flaw is known or still undisclosed. Our sensors record sources doing that probing. A firewall rule using the feed can deny a listed source before its next connection reaches your service, without needing to recognize the exploit itself.
A flaw may be tested next
A weakness in any exposed interface gives later exploit traffic a path into a sensitive service.
Act before your own alert
The feed can carry sources already seen by our sensors, so a local connection need not be the first warning.
Edge enforcement
Defend your edge
The feed loads matching rules into your firewall. Listed sources are intercepted before crossing the edge; traffic with no match continues to your services.
Where this feed fits
Use the observed source list where your existing edge controls meet these reachable services.
Review scanner sources at the edge of a reachable trading interface. Keep counterparty allowlists and session controls in place.
Apply the list around exposed market data services. Check that subscribers and upstream sources still have access.
Use the feed in front of a reachable payment security service. Access to the service should remain limited by its own rules.
Review the list on paths used to administer financial systems. Approved staff still need identity and device checks.
Apply the list where an operations database is exposed. Confirm the applications and maintenance networks that need to connect.
Use one source list across trading, payment, and data gateways. Set exceptions for each service instead of giving them identical access rules.
