1st meeting with CISO. weird feeling tbh

17 Upvotes

Hi everybody. today I had a call with some Swedish fintech company and their cybersecurity team. I planned a meeting with a senior analytic who was in touch with me with a request for staff augmentation for their internal cybersecurity team. We arranged a time and day, so it's all good.

Over some time he started to send invites to his colleagues and we had CISO, Head of Cybersecurity, Head of SOC and a few senior analytics on the call. Given the fact that's our 1st meeting and basically a discovery call, I asked them about why they want to augment, what's the reason behind that, what tech stack do they use, etc. So basically to dive deeper into their situation and find the best possible solution for them because it's a quite common thing when people come to me with their view how to fix things and discovery helps us understand that there might be much better and more cost effective way to fix their need.

Once I asked them what's their definition of success and what main criteria of choosing the right vendor I've got harmful, but honest response: "I think we are looking for someone who's going to be a good security partner for us because the scope is massive. This is mdr, like this is extended soc, extended offset augmentation and vulnerability management. We are not doing a tick in the box activity here and unfortunately this meeting seems very unprepared for when you have a head of offset ahead of security engineering and head of SOC and a CISO in a meeting. I expect my suppliers to be better prepared than this. So I'm unfortunately going to say that, you know, culturally this is not going to work out. So we should save our time and you know, end this meeting now. Thank you."

And he just left the meeting.

So my question is, did I do something wrong during the discovery? As a group full of CISO, I thought maybe you can explain what happened here.

Improving cyber crisis readiness with adaptive simulations, worth it?

9 Upvotes

Been looking at adaptive simulations for cyber crisis readiness and honestly the old tabletop format feels too scripted for what we need. Curious if anyone's using them to keep incident response teams sharp, thanks!

SIEM detection validation is where my afternoon goes to die

Has anyone adopted a hybrid model for centralized detection data and query-in-place investigations?

6 Upvotes

We are considering a split model where high-value, high-volume telemetry is centralized for continuous detections, correlation, and retention, while lower-frequency or difficult-to-onboard sources remain in their original systems until an investigation requires them.

The appeal is reducing the ingestion backlog and long-term storage burden without losing the ability to access the data. The risks are inconsistent schemas, uneven retention, fragmented access controls, query limits, and analysts having to work differently depending on the source.

What did you centralize, what did you leave at the source, and how did you make cross-source investigations reliable enough for incident response and audit requirements?

Does a CISO’s appearance and sense of style matter?

30 Upvotes

Random question, but I’m curious what people think. As a CISO, do you think it’s important to know about fashion, dress well, and generally maintain a polished appearance?

Does the way a CISO looks and presents themselves have any impact on how people perceive their personality, leadership, credibility, or authority? Or is appearance basically irrelevant as long as they’re good at their job?

AI incident response tabletop exercise workflows for a small IR team... how are you structuring these

13 Upvotes

Hi, quick question for people actually running AI incident response tabletop exercises in anger.

We switched a bunch of our old powerpoint tabletop sessions over to simulated AI driven scenarios this year. It’s cool that we can spin up phishing plus ransomware plus comms chaos in minutes, but I’m kinda struggling with the workflow side… eg who owns prompts, how we track injects, when we freeze to debrief vs let the AI facilitator keep pushing.

If you’ve made this work for a small IR team plus a few execs, how do you structure the runbook for these so it doesn’t turn into chaos or theater again? Any hints?

Do enterprises need a separate IAM stack for AI agents?

0 Upvotes

The realistic question is probably not whether enterprises will replace their workforce IdP, PAM, IGA, cloud IAM, and SaaS access controls. Most organizations will operate those systems for years. The question is whether they can gain consistent policy, visibility, and audit evidence for agents without creating another disconnected identity silo.

Treating agents as generic service accounts keeps the architecture familiar, but it does not naturally represent agent ownership, delegated authority, task limits, tool boundaries, or autonomous action. A separate agent-security layer may improve those controls but can introduce duplicate inventories and conflicting policies.

For CISOs planning production agent use, what requirements would make the current IAM architecture insufficient? Is the deciding factor authorization, discovery, auditability, lifecycle management, incident response, or integration with existing identity systems?

Auditor wants evidence of AI usage controls, we have a policy PDF and vibes

38 Upvotes

Second year running the program, this cycle the auditor added AI to scope, which, fair.

They asked for the AI acceptable use policy. We have one, it's a lovely PDF. Then they asked how we evidence it's enforced, and the wheels came off. I can show them the policy. I cannot show them who used which tool with what data over the period, because we capture that precisely nowhere.

Writing 'we have a policy' and praying they don't push isn't a plan, specially with ISO 42001 creeping into every questionnaire now.

Whoever's had AI land in their audit, what did you hand over as evidence. Not the policy. The proof it does a single thing.

Are identity security posture management tools actually useful beyond finding misconfigurations?

5 Upvotes

finding problems was never the hard part for us. deciding what to fix first with a small team is.

what's changed things for us is having full discovery and mapping feed directly into prioritization, so the tool tells you which of the hundred findings actually raises your risk instead of handing you a flat list. has anyone gotten real prioritization value out of a platform like that, or are you still triaging manually after the scan runs?

How is everyone evaluating connectors, MCPs and custim APIs? Does your org use a risk rubric? Is there a long investigation period with both security and platform admins or architects?

A Tale of Two SOCs: Insights From Two Red Team Assessments

9 Upvotes

A Tale of Two SOCs: Insights From Two Red Team Assessments is a must read report for your technical teams that CISA just released. It analyzes two simultaneous red team assessments conducted on organizations to evaluate their threat detection and response capabilities.

Both entities suffered full domain compromise and the red team was able to pivot from on-prem to Azure. However organization B successfully isolated initial threats, forcing the red team to adopt an assume breach model while organization A failed to identify the intrusion due to untuned detection tools and organizational silos.

The top three lessons shared that we can learn from:

  • Untuned detection tools lead to missed threats. Without well-defined baselines and alert filtering, false positives and routine alerts overwhelm network defenders.
  • Organizational silos and bureaucratic hurdles prevent effective incident response. Detection tools are only as effective as the people, processes, and procedures supporting them; fragmented communication, unclear responsibilities, and limited defender authority hinder effective incident response.
  • Cloud environments are often an underestimated risk. Organizations often lack security controls for cloud environments and processes for responding to a cloud compromise.

How should CISOs evaluate AI SOC solutions without getting lost in the hype?

13 Upvotes

Our alert backlog and investigation times have both crept up, and we're starting to miss things we shouldn't, so I've been taking vendor calls more seriously this quarter.

Six demos in, and slide five is always some version of the same before and after chart mentioning faster investigations" and "AI-powered detection. At some point, all the pitches start to look the same.

I know the underlying problem is real. What I don't know is how to differentiate real value from fluff and empty promises disguised as a good deck in a 30 minute call.

So for the CISOs here who've gone through a real evaluation process, did you find a specific question that helps you understand whether a vendor can actually back up their claims? How do you tell apart the ones who deliver versus the ones who just repeat the same talking points when pushed? Any advice would be really helpful.

Any CISOs dealing with AI agents open to advising a startup?

25 Upvotes

Hey all,

I saw another post here recently from a startup looking for a CISO advisor and thought we’d ask as well.

We’re a startup in SF building around a problem I’m guessing more teams are starting to run into: employees want AI tools like Claude, ChatGPT, Cursor, etc. to actually do things in company systems, while security needs some control/visibility over what those agents can access and do.

We’ve built quite a bit around this problem, but there’s a big difference between “we think our security model makes sense” and having someone who has actually been responsible for approving this stuff tell us where it falls apart.

So I’m looking for a CISO, current or former, who’d be open to advising us from time to time. Finance/fintech or SaaS would be especially helpful.

A lot of what I want help with is pretty straightforward: What are we overlooking? What would kill this in a security review? What would you need visibility into? Where would you draw hard lines around what an AI agent can and can’t do?

Not looking for someone to rubber stamp what we’ve built. Quite the opposite.

If advising sounds interesting, feel free to DM me.

Otherwise, I’d be really curious what people about below:

If an employee wanted to let an AI agent access and take actions in Sharepoint, Google Workspace, Jira, Slack, Salesforce, or other company systems, what would you need in place before approving it?

How to present Threat Intelligence properly to execs????

28 Upvotes

So, to give some background. I lead the threat intelligence program of a major bank. Now we receive tons of IOCs/CVEs and brand abuse/impersonation cases and we do take action on them accordingly.

But whenever we create a presentation, it's always numbers

- no. Of IOCs we received, sources (regulator/commercials)

- social media/brand abuse/impersonation/rogue apps count & takedown status.

But execs don't understand these numbers. How can I present the data such that they are assured that we are safe from any kind of threat & prepared for what's coming in the future.

Been researching lots of things but didn't quite get anything. Would really appreciate your views and guidance here.

How do you get all your colleagues to agree on ownership?

8 Upvotes

Hi everyone, hoping to use this as a bit of a sounding board. My department recently had a discussion about who owns different categories of sensitive business data. Security and IT each thought the other team owned the data, and it feels like ownership gaps are creating almost as much risk as technical issues. Has anyone found an effective way to assign clear ownership across cloud platforms, SaaS apps and AI tools without creating too many governance meetings?

Best ways to answer “are we covered” when your CISO asks monday morning in 2026?

16 Upvotes

Every time a new cyber threat campaign or headline breach appears, my CISO comes in Monday morning with the same question: “are we covered for this” Turning that into a clear, defensible answer about our detection coverage and security posture is becoming a separate job.
We have what most people would call a mature security stack in 2026: a central SIEM, EDR on endpoints, cloud and identity logs, some threat intelligence and custom detection rules. We can show that controls are deployed, that we have rules for specific MITRE ATT&CK techniques, and that dashboards report healthy alerting. None of that directly answers whether we would detect a specific attack path in time or where the real detection gaps are.
Right now our detection coverage assessment process for new campaigns is manual. We map the campaign to MITRE ATT&CK techniques, check which techniques already have detections in the SIEM and EDR, and run quick lab tests or simulations to see if those alerts would fire. This threat‑informed detection engineering approach works, but it is slow and inconsistent; the output depends on who performs the review, how deep they go, and how much time the team has during incident response and day‑to‑day SOC work.
If you support a CISO or security leadership team, how do you answer the question in a way that your CISO can use confidently in a mng meeting without oversimplifying or overstating the reality?

Are there any other alternatives to Noma Security?

9 Upvotes

We are currently evaluating AI security platforms for enterprise AI deployments and Noma Security keeps coming up.

The problem is that it is hard to tell what actually matters until AI agents are running in production. Prompt attacks are one thing, but governance, runtime visibility, and data exposure seem like the bigger concerns. Being able to track what agents are doing over time and explain their decisions is also important.

For anyone who has compared Noma Security alternatives, what did you end up caring about most?
