Our story
We test the way it should be done.
Vigilant takes on a small number of tests at a time, puts senior people on every one, and gives each enough time to chase a finding to the end, rather than close the ticket and move on.
The problems that matter are never the ones a scanner hands you, and they are never found in a hurry. So every finding we report has been checked by a person, in your setup, before it reaches you.
We have tested for startups, large companies and government groups on multiple continents.

- Manufacturing

Four promises we do not bend on.
Security testing is a trust business. These are how we earn it, and why clients come back.
We test by hand
Tools are where we start, not where we stop. A person confirms every finding we report is real in your setup.
We report impact, not a list
We tell you what an attacker could really do, and which few fixes remove the most risk for the least work.
We stay until it is fixed
A test is not done when the report lands. With the Complete package, we retest your fixes until they hold.
We say when you do not need us
If a pentest is not what you need yet, we will tell you. It costs us a sale and earns the next three.
Leadership
Led by someone who still does the work.
Before founding Vigilant, Nathan Kramer led the offensive security team at one of the top consulting firms in the United States, running internal and external network testing, web and API assessments, social engineering, and wireless work for clients across healthcare, finance, manufacturing, and government.
He has consulted for more than 450 companies. He held the top 1% on Hack The Box, contributes to their content library, and mentors through EC-Council. He is a member of InfraGard and the Cybersecurity Council of South Dakota.
