VulnU Membership · A private community for security professionals

Security is hard.
Don't go it alone.

Your team doesn’t have to be your entire network. Trade experience, share useful work, and build relationships that last beyond your next job.

$499/year or $49/month · Team memberships available

From Matt Johansen and Vulnerable U.

The newsletter reaches 38,000+ readers. Membership gives the conversation a home.

Inside the membership

More perspectives.
Fewer dead ends.

A place to ask the follow-up question, hear how someone else handled it, and contribute what you know.

01 / PEER PERSPECTIVE

A second opinion before you commit.

Buying a tool? Changing a process? Ask about the parts that never make it into the sales deck: rollout headaches, maintenance, and what people would do differently.

Vendor experiencesArchitecture decisionsLessons from the rollout

Go beyond the demo

What did this cost to run after the pilot?

What broke during rollout?

Would you buy it again?

02 / AI IN PRACTICE

Get past the AI demos.

Put the tools to work.

Compare coding-agent setups, investigation workflows, and automations you’ve actually tried. What saved time? What needed fixing? How did you check the results?

Explore together

Coding agents · Detection · Investigation

Understand where they break.

Dig into prompt injection, agent permissions, and data exposure. Discuss current research and share results from authorized testing of AI applications.

03 / SHARED RESOURCES

Show what you built.
See how others did it.

A useful script is better when you can ask its author a question. Share your work, explain where you’ve tested it, and help each other adapt it.

Member contributions, with the context that makes them useful.

04 / CONNECTIONS

Find more than a job title in common.

Find people through the member directory, start a direct conversation, or get to know someone over books, games, music, and the occasional pet photo.

Good professional relationships don’t have to start with a networking pitch.

Hiring?

Share an opening and explain the work behind the job description.

Going independent?

Talk consulting, startups, and finding your first customers.

05 / CAREERS & OPPORTUNITIES

Get a clearer picture of your next move.

There’s more to a role than its listing. Exchange career experiences, meet people in other corners of security, and learn what a different path could look like.

Browse the public job board for free. Join for the conversations around it.

06 / NEWS & RESEARCH

Go beyond the headline.

VulnU newsletter issues land in the community, ready to discuss. Add a missing detail, question a claim, or explain why a story matters in your corner of the industry.

The newsletter and YouTube videos stay free.

Keep the discussion going

What does the original research actually show?

Does this change anything for your team?

What’s missing from the coverage?

New to Vulnerable U?

Keep it useful.

Self-promotion belongs in shameless-plug. No unsolicited sales DMs.

Respect the people.

Different experience levels are welcome. Challenge ideas, cite your sources, and keep confidential work private.

Make it fit your day.

Join from your laptop or phone. Follow the discussions that interest you and choose your notifications.

Buying through work

Put your development
budget to work.

For you, or your team.

Individual: $499 per year or $49 per month.

Teams: $499 per person, per year. Five seats start at $2,495.

Copy a note for your manager

Subject: Professional development request: VulnU Membership

I’d like to expense a $499 annual membership to VulnU, a private community for security professionals.

I plan to use it to discuss tool evaluations, learn from other practitioners, and bring relevant ideas back to our team.

Can this come from my professional development budget?
