Coming soonNorthmark: fixes for the pen test findings that keep coming back

Security and compliance tools for small IT teams

Durendal was started on the belief that a 20-person company should be able to defend itself as well as a 2,000-person one.

Every tool is built from a real problem or need, drawn from 20 years of hands-on IT work, and priced so small and medium-sized businesses can actually use it.

Solutions

Each one started as a problem we ran into on the job.

Sealing the evidence you hand over

Overview

Pulls screenshots, PDFs and your own write-ups into one numbered, consistent packet for an auditor, a client or your own team. Once you issue a packet it's sealed, so anyone can check that nothing in it changed.

Field note 01 / 03 · Why I built it
I ran a company's annual SOC 2 Type II audit. The auditors' portals got better every year, but our side was still a pile of SnagIt screenshots, exported PDFs and notes typed up by hand.

Watching every link you publish

Free tier on the way

Overview

Records where every link on your website leads today, then tells you when that changes. A link that moves to a new vendor page gets a low-key notice. A link that now lands on an adult site gets an urgent alert.

Field note 02 / 03 · Why I built it
A former client's website move went wrong, and one of their links started sending visitors to an adult site. It caused real trouble for them and for the customers who clicked it.

In development

Overview

Takes the common problems a penetration test turns up and gives you fixes you can run, from the command line or a simple app, without hours of research first.

Field note 03 / 03 · Why I built it
Our pen testers kept telling me how many clients had the same misconfigurations year after year. Many were easy to fix. The teams just never had time to get to them.

Why I build these

I've worked in IT for over 20 years, in consulting, project work, directing teams and most roles in between, much of it in and alongside small businesses. The tools that would have helped us were often built and priced for large enterprises, so we found workarounds and rebuilt the features we needed ourselves.

At a small company, the person running security is often also running the help desk, the vendor contracts and the audit. The right tools let one person cover all of that and still do it well.

That's why the prices start low. I want Durendal to succeed, but not by squeezing the businesses it's meant to help.
