Ryan Erb

Systems engineer and developer in Park City, Utah. I fix things, build things, and keep banks out of trouble with their examiners. Here are the products I've built, the tools and scripts I give away, and the books I keep handing to people.

About Ryan

Today I work with 30 banks across the Midwest. I write their policies, sit with them through every exam and audit, serve on their IT committees, and explain compliance to the people who need to understand it. I also build tools that watch for configuration drift and give IT committees the reports they need to make informed decisions, clean up their environment, and reduce security risk and exposure.

I acquired these skills on the job at Celtic Bank, through many audits and exams and by working with compliance mentors. I was the IT Manager for twenty-one years, from a $2M startup to over $1B in assets. Every server, every network, every exam was mine. Later, at RESULTS Technology, I found out most institutions are fighting the same handful of problems.

Before the bank, I was a programmer. I wrote my first real code in 1994 and started Erb Networks in 1995. I still write code today, and I still build the servers and networks it runs on. LakeMonster started as a personal problem. A few times a year I was calling the lake to ask if the ice was off, what the water temperature was, and what the weather and conditions were like. Nobody had that in one place, so Dillen and I worked long and hard on what everyone said was impossible. ioJump, AuditHat and DriveCrazy came about the same way, along with the other projects on this page. They are what happens when the developer, the infrastructure guy and the compliance guy are the same person.

What I do

I've worked every layer of the stack since 1994, so I don't have to hand your problem off to someone else.

I keep an eye on what's coming. Most of the products on this page started because I saw a need a little before everyone else did.
