CounterTack

CounterTack, Inc. was a Waltham, Massachusetts endpoint detection and response (EDR) vendor whose Sentinel and Endpoint Threat Platform products applied behavioral analysis, memory forensics and machine learning to detect zero-days, rootkits and advanced persistent threats. In June 2018 CounterTack acquired its channel partner GoSecure, a managed detection and response (MDR) provider, and in March 2019 rebranded the combined company as "GoSecure powered by CounterTack"; the CounterTack name has since been retired in favour of GoSecure, which today markets a managed extended detection and response (MXDR) service and the GoSecure Titan platform covering EDR, IDR, NGAV, SIEM and professional services. The CounterTack surface is therefore historical: countertack.com still resolves to GoSecure infrastructure but serves no valid certificate, and the living platform is customer-only behind a Keycloak single sign-on at titan.gosecure.net.

CounterTack publishes 1 API on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, Endpoint Security, and Endpoint Detection and Response.

CounterTack’s developer surface includes support, authentication, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/countertack: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: CounterTack now trades as GoSecure, and its live Titan API host api.gosecure.net returns HTTP 401 on every path
    probed — including /robots.txt and every /.well-known/ path — while the Titan console sits behind a Keycloak tenant login,
    so the contract and reference are reachable only by an existing GoSecure customer.
