We build software for people whose findings have to stand up when somebody else examines them: investigators, analysts, security teams and journalists. Our tools gather information, connect it and keep every fact tied to the source it came from. They run on your own device, and what you create stays there.
Durandir Harness brings our tools together in one case. Durandir Agent turns an objective into a plan and checks the results against the evidence. Durandir Intelligence, Durandir Counterintelligence and Durandir Cybersecurity cover identities and infrastructure, personal exposure, and the security of websites, APIs and networks. Our own team uses the same software to carry out cybersecurity, exposure and compliance audits for organisations.
What we stand for
- Evidence before conclusions. Every finding keeps its source, and confirmed matches stay apart from people who only share a name.
- Your work stays yours. Our products process data on your device, not on ours.
- Power with limits. Safeguards stop what the law prohibits, and sensitive capabilities are reserved for those authorised to use them.
- Software that lasts. We would rather build one tool that holds up for years than many that do not.
Why Zaragoza
Durandir Technologies is based in Zaragoza (Saragossa), in Aragon, and that is no coincidence. In The Song of Roland, Zaragoza is the last city in Spain still holding out against Charlemagne. The plot that ends at Roncevaux, where Roland falls with his sword Durandal, is hatched here.
The Ebro valley has long been one of Europe's historic military frontiers, and that legacy is still alive. Zaragoza is home to the Zaragoza Air Base of the Spanish Air and Space Force and to a major Spanish Army complex that includes the General Military Academy and the San Gregorio National Training Centre. Aragon also leads the Aragón Defence Hub, which brings public institutions, industry clusters and companies together to build the defence ecosystem of the region.
It is a fitting place to build security and intelligence software, and a daily reminder of the responsibility that comes with it.
As a curiosity, the Aragonese Pyrenees are home to the Brèche de Roland (Roland's Breach), a huge gap in the ridge on the border with France. Legend has it that Roland, trying to break Durandal before he died, struck it against the mountain and split the rock open.
The name
Durandir takes its name from Durandal, known in the Spanish tradition as Durandarte, the sword of Roland. Its name is often translated as "the unbreakable" or "the enduring", which is what we want our software to be. Our logo reinterprets the pommel of the sword and also forms a D.
