Response Bridge  /  parent company

Three tools for the people who defend systems.

We build and run Sentendra, DetectionLint and DummifAI: incident response, detection-rule review, and realistic data to build against. Each one stands on its own. They were designed to stand next to each other.

01  /  the products

Each solves one problem, properly.

None of them is a module you have to buy the others to use. Pick the one that hurts most today; the rest will be there when the next problem shows up.

DetectionLint

02  /  how they fit

Build it, review it, then respond to it.

The same defensive team tends to need all three at different points in the week. Here is where each one sits.

  1. before · DummifAI

    Build against real-looking data

    Seeded records, log streams and webhook events to develop and demo against, long before production data is allowed anywhere near it.

  2. during · DetectionLint

    Review every rule before it ships

    Each detection gets a score, a false-positive estimate and a list of fixes, in the editor, over the API or as a CI gate, so noisy rules are caught before they reach the queue.

  3. after · Sentendra

    Work the alerts those rules raise

    Alerts land as cases with their evidence attached, the team works them to a close, and the record stays for the next review.

03  /  how we work

A small company with three honest products.

Hosted and looked after
Every product is fully managed SaaS. We run it, patch it and ship updates continuously, so there are no maintenance windows on your calendar.
Composable, not bundled
Buy one, or all three. Nothing is held back to push you into the others, and each has a free way in.
Built for defensive teams
Detection engineering, incident response and realistic test data: the working surface of a modern security team, and nothing that isn't.
