We're reviewing data security platforms and Varonis is obviously on the list, but I don’t want to default to it just because it’s the name everyone knows.

Our environment is pretty SaaS-heavy, with a lot of unstructured docs and shared data rather than neatly structured database fields. Classification accuracy is a big priority for us. I also don’t want to bring in another tool that has the security team spending half their time sorting through false positives.

For anyone who’s evaluated Varonis competitors recently, what else made your shortlist? And once you actually got into the POC, what separated the stronger options from the rest?

just concluded a 60 day trial POV on the same M365 tenant all three on top of Defender for a 500 seat finance shop. we're doing this only because of vendor email compromise and clean BEC slipping through our current gateway. there's alot at stake so we need to get this right.

results so far are as follows. Abnormal caught the most payloadless BEC and had the lowest false positive rate of the three and Checkpoint was close, is cheaper for our size and can run inline with real attachment sandboxing while still protecting internal mail, which Abnormal does over API only. Sublime was very good at detection and far more configurable, only problem is it wants an engineer to run it. none of them is a clean win. For anyone who picked either of these in the last year, which would you recommend?

Hello, I apologize if this is the wrong place to ask but I can't help but wonder why my pc made an outbound connection to whatever IP last night and need help figuring out if this is a normal event.

The only other info I could provide is that MsMpEng.exe was let through the firewall 1 second before lsass.exe, and the information I've gotten about the IP is that it's associated with CloudFlare.

The Windows Filtering Platform has permitted a connection.

I am trying to distinguish meaningful capability changes from AI terminology.

Traditional AppSec can already scan code, dependencies, secrets, CI/CD, and infrastructure. The Agentic AppSec pitch is that a system can combine those signals with application context, identify the risks that are exploitable and business-relevant, help create and validate fixes, and use remediation lessons to improve prevention during future AI-assisted coding.

For teams that have evaluated this, did it materially improve outcomes or mainly automate pieces of an existing process?

Being honest with myself about this one. We rebranded to risk based vulnerability management, RBVM, about a year ago. New scoring, new dashboards, new language in every deck. Looking back, we are patching roughly the same things in roughly the same order we were before. Just with better looking justification attached now.

Which either means our old prioritization was already directionally fine, or it means we relabeled the old model instead of actually building a new one, and I do not know which. For anyone further along than us, did RBVM actually change what gets fixed first and how fast, measurably, or did it mostly just change how the program gets talked about? A real answer please, not the version that goes in a case study.

Same experience here. The rebrand mattered more for audit and vendor conversations than it did for actual patch order. I do not think that is necessarily a failure though, having a defensible answer has real value even without changing outcomes.

For us it did change outcomes, but only because we paired the rebrand with actually ripping out CVSS as the primary sort key. If you keep CVSS as the default sort and just add RBVM language on top, nothing structurally changes.

Patch order actually changed for us once we moved our default queue sort away from raw CVSS toward the risk score built into Nucleus. Lower severity KEV listed findings started jumping ahead of higher severity ones with no exploit. Making that switch is what turned RBVM from a label into an actual behavior change for us.

seeing more vendors position "guardian agent" style approaches, where an agent monitors and constrains other agents dynamically, against traditional static guardrails baked into the prompt or model layer. curious what people with actual production experience think about this tradeoff rather than what the marketing pages claim. static guardrails are predictable and auditable but brittle against novel behavior nobody wrote a rule for.
a guardian agent approach can theoretically adapt to new behavior, but it introduces its own attack surface and adds a layer of complexity that could fail in ways that are harder to reason about during an incident. has anyone run both in production long enough to have an actual opinion, rather than just a vendor's pitch deck?

Wanted to see how others are handling this one.

tldr; Kubeflow Pipelines has an unauthenticated SSRF in its legacy /_proxy/ route.
Fixed in 2.17.0 (the fix rips out the generic /_proxy/ middleware entirely).

The part that caught my attention is that any target could be reachable from the network namespace, meaning an unauthenticated attacker effectively borrows the pod's network position. This allows reaching the cloud metadata endpoint and pulling the IAM credentials tied to the node or pod's role. From there the blast radius is whatever that role permits.

Patching is obviously the answer where possible. For those who couldn't patch immediately, what compensating controls did you implement? Things I've been weighing:

• Network policy / egress restrictions on the frontend pod so it can't reach internal addresses (e.g., 169.254.169.254, kubernetes.default)
• Blocking the /_proxy/ routes at an ingress WAF or IPS

Did anyone find a clean way to neutralize this at the network layer without breaking the application?

Most cybersecurity products are designed to protect identities, endpoints, applications, cloud environments and data. These all are important, but encryption still exposes metadata through traffic timing, routing behaviour, and connection patterns etc.

This creates a couple questions I do not see discussed enough

How much security is being left unaddressed because the underlying communication transport is generally treated as a fixed dependency rather than part of the security architecture?

For high-assurance environments such as government, critical infrastructure and defence, the network itself may be observable, disrupted or operated through infrastructure outside the organisation’s direct control. In those environments, protecting content doesn’t fully address the threat.

Im interested in the community’s view on the following

1. Is transport-layer observability treated seriously enough in current cybersecurity architecture?
2. What current technologies address this problem effectively and what gaps remain?
3. Do you expect secure communications infrastructure to become a larger cybersecurity category over the next five - ten years?

Our on-call rotation used to be about incidents and reliability. Now a growing chunk of it is triaging security tickets that get auto-assigned to whichever team owns the service, regardless of whether the finding is actually a real risk. Half the time it's a CVE in a transitive dependency that isn't even loaded at runtime, and the security team means well but doesn't have the context to know that, so we end up individually debunking tickets one at a time.

Has anyone solved this by getting security findings pre-validated for actual exploitability before they hit engineering backlogs? Feels like the fix has to happen upstream, not on our end.

We run a large web application portfolio and the volume of findings coming out of our scanners has completely outpaced what our security team can manually review. Every app team wants their own report, every app is built slightly differently, and there's no way our analyst headcount grows at the rate the finding volume does.

Right now it's a lot of manual triage per application, which doesn't scale and burns the team out fast. It's especially bad when two apps get flagged for what looks like the "same" vulnerability class (say, an XSS or injection finding) but the actual exploitability is completely different depending on how each app handles input and what's sitting in front of it.

We've tried building a standardized triage checklist to speed things up, but it only helps at the margins. The real bottleneck is still a person having to look at each finding and decide whether it's actually reachable and dangerous in that specific app's context.

For anyone running web app security at this kind of scale, how are you keeping remediation timelines reasonable without just adding more analysts? Anyone found a triage workflow that actually holds up as the app portfolio grows?

Writing a policy saying agents are monitored and controlled is one thing, producing something an auditor would accept as proof it's working continuously is another. Point-in-time reviews clearly aren't enough given how fast agent behavior and permissions can change, but I haven't found a clean standard yet for what continuous evidence should look like.

If your org has been through an actual audit involving AI agents, what did you end up providing that satisfied the auditors? Trying to build toward something real, not guess at what will hold up.

Sat through enough demos this year that I've started using a short checklist to filter vendors before committing real evaluation time. Sharing in case it's useful to others drowning in this category:

What do you actually see without touching our architecture? If the honest answer involves an SDK, a proxy, or code changes, that's not "runtime," that's integration work with extra marketing.

Do you detect intent/behavior, or just pattern-match inputs? Input filtering alone misses anything novel; ask for their false negative rate on out-of-distribution attempts.

Can you map what an agent can actually reach, including delegated calls to other agents/tools? A lot of platforms stop at "here's the top-level permission grant."

What counts as your "evidence" for compliance purposes? A log export is not the same thing as continuous, structured evidence mapped to controls.

How fast is time-to-value in a real environment, not the demo environment? Ask specifically what breaks or slows down once you're past the sandboxed POC.

What happens across our actual mix of agent platforms? Homegrown, cloud, SaaS, and endpoint agents behave differently; a vendor that only covers one is a partial answer.

None of these are trick questions, but you'd be surprised how many vendors get vague fast once you ask them directly instead of watching the scripted demo. Anyone have other questions they've found separate the real platforms from the repackaged logging tools?

We had an incident review last month that started with "wait…we have an app doing what" Turns out someone in ops had used Lovable to build a customer intake form months ago, wired it straight to a live database, no auth in front of it, completely public.

Nobody in security knew it existed because it never went through any provisioning process, there was no repo, no ticket, no deployment request. It just appeared on the internet.

We started asking around and found two more instances across other departments, a survey tool built on Replit connected to a shared data store, and a landing page someone spun up on Vercel that had an exposed API key sitting in the client side code.

None of these showed up in our asset inventory because none of them touched our normal SDLC. Apparently we're not alone, researchers found something like 380,000 publicly accessible apps built this way, with a meaningful chunk leaking actual sensitive company data.

Has anyone found a reliable way to catch these before they turn into an incident rather than after someone stumbles onto them?

I am currently analyzing the architecture and security policies of an AI call assistant app and found some potentially critical flaws. I would like to get the opinion of developers and security experts on whether the following scenarios should be classified as bugs or security risks:

​In a call screening app, if a user refunds their premium subscription via the Play Store, should the backend virtual number be auto-released? If it stays assigned and continues handling calls after expiry, is this considered a bug?

​If an app's UI shows call screening as 'Off' for expired users, but carrier-level Conditional Call Forwarding (CCF) is still active on the backend number (meaning calls bypass the app and are still answered by the server) - is this UI vs. network state mismatch considered a bug?

​In an AI call assistant app that allows custom instructions - if setting an instruction like "on code 123, ask for number and bridge call" allows outbound calls from the platform's own server number to any external number, is this a valid prompt injection / toll fraud vulnerability?

​If selecting a premium voice shows a paywall, but pressing 'Back' + 'Save' still saves the premium voice on the server for the offline forwarded number (while the app UI still shows it as locked) - is this a client-side validation bypass/vulnerability?

​What are your thoughts on these? Any advice on how these architectural issues are typically categorized and handled would be highly appreciated!

Every time a new campaign hits the news or shows up in one of our intel feeds, we go through the same painful cycle.

Someone flags it in a channel, we pass it to the team, and then the work starts: reading through the write‑up, pulling out TTPs and IOCs, mapping them to our stack, and then trying to turn that into actual detection logic. By the time we have a rule in the SIEM, tuned enough that it will not blow up the queue, the campaign has already been around for days or weeks.

Our setup is pretty standard: one main SIEM, a couple of EDRs, cloud logs, identity logs, and a small detection engineering function that also wears other hats. Nothing about our environment is unique, but the time from “new campaign reported” to “confident detection in production” still feels too long.

Right now a lot of this is still manual: analysts translate reports into hypotheses, detection engineers write queries, then we do limited testing in lower environments before pushing to prod. It works, but it does not scale, and we always have a backlog of “campaigns we should cover” that never quite gets cleared.

What I am trying to understand is how other teams have shortened this loop. Are you relying mostly on vendor‑provided content from your SIEM/EDR, internal playbooks, some kind of threat‑informed detection engineering process, or a separate platform that takes campaign intel and helps you get to a runnable rule faster? Curious what has made the biggest difference for you in terms of days or hours saved between seeing a new threat and having real coverage in place.

Most dark web monitoring tools seem designed around a simple model: one company monitors its domain and employee identities.

Legal tech platforms are more complicated.

One platform may serve hundreds of law firms, each with separate:

• Clients
• Users
• Matters
• Credentials
• Confidentiality obligations

That creates an interesting architecture problem.

Detecting an exposed credential is only part of the job.

The platform also needs to know:

• Which tenant owns it?
• Who should receive the alert?
• Does it relate to a specific matter?
• How do you prevent one firm's exposure data from appearing in another firm's workflow?

Webhook-based alerts also seem more useful than periodic polling when a credential or session token needs attention quickly.

For teams building multi-tenant security features, how do you approach alert routing and tenant isolation?

Would you build monitoring internally, or integrate a specialized API and focus on the product workflow?

Hi everyone,

I am researching how LLMs find vulnerabilities and why they hallucinate so much. I would love to get your thoughts on two major challenges in this area:

1. Exploit Verification: In your experience, can AI hallucinations in source code analysis be completely eliminated if every flagged vulnerability is automatically validated by generating and running a working proof-of-concept (PoC) exploit in a sandbox? Has anyone tried this workflow?

2. Data Privacy (Cloud vs. Local): To prevent source code leaks, is a local-first approach (like using Ollama) mandatory for real-world security audits? How much does performance drop compared to cloud models when analyzing complex code logic?

Thanks for sharing your insights!

I’ve been mapping our AI exposure and the OAuth side was way worse than I expected. I went in assuming the main shadow AI problem would be people dropping company or customer data into ChatGPT and other consumer LLMs on personal accounts but the third party AI apps and agents were worse.

We found more than 30 AI tools and assistants with OAuth grants into Google Workspace and M365. A good number still had live read access to mail, Drive and calendars months after anyone had used them. One meeting notes AI had held access to a shared calendar since March.

We block obvious consumer LLM domains with Palo Alto category filtering, but that does nothing for a contractor on a personal laptop or an OAuth grant coming through a normal Google login. Purview catches some activity inside M365, but it didn’t give us visibility into these external AI apps with standing access. We only found them by exporting the OAuth grants and reviewing them manually.

For teams past the block everything stage, what are you using for proper shadow AI discovery?

I remember when browsing a site like PayPal would prominently display a green bar with the verified company name in the address bar. The logic was clear: it helped users distinguish paypal.com from a lookalike phishing site like paypa1.com.

Nowadays, browsers just display a neutral lock icon (or tuning icon), tucked behind a click.

I'm looking for an actively maintained repository of Semgrep rules focused on detecting malicious/suspicious behavior, not regular vulnerabilities.

I don't want to write hundreds of rules myself. Are there good rule collections for this purpose?

Our browser agent rejected direct jailbreaks in testing, but then obeyed an instruction hidden in a vendor-page footer. An untrusted page content crossed into a privileged tool call and placed a canary secret in an outbound request. Unit tests didn’t pick it up because they covered chat input, not content provenance after browsing. 

We are adding source labels to every content block, narrower tool scopes, destination allowlists, canary-secret detection, and egress controls that do not rely on the model making the right choice. I’m also pushing for tests that mix trusted instructions with hostile retrieved content. What safeguards have actually stopped indirect prompt injection in browser agents, especially when a legitimate task needs outbound tool access?

I just learned about some of the insanely cool things you can do using AI, like you can literally just make an app/software that serves a need for you and is completely tailored to your preferences.

My question:

Does having all these AI-generated apps on your phone/computer create potential security risks? (Assuming you aren't doing much of anything with cloud storage apps and you're not sharing/distributing the software to anyone else.)

EDIT

Wow, lots of good and interesting answers already. I'm really glad I asked this question before I started blindly using it to create a bunch of random stuff apps and software lol.

Thank you to everyone who posted!

MFA stops the initial compromise but does nothing once an attacker has a valid session token, and we've seen that gap exploited more than once this year.

what's actually held up for us is treating device-bound sessions as the default rather than an optional hardening step, so a token can't be replayed or reused on another device even if it's stolen. token binding alone wasn't airtight against a determined attacker. what's your setup, and has anything meaningfully cut down on token replay for you?

had an incident where the attacker used valid credentials from a legitimate device and the login itself tripped zero alerts.

attackers aren't breaking in anymore, they're logging in, which means login-time signals alone were never going to catch this. everything downstream was the tell: unusual data access, then a permission escalation attempt about twenty minutes later. what signals are you watching post-authentication that actually catch this before real damage happens?

running a handful of scanners across infra and application code, containers included in that mix, and the same underlying vulnerability shows up as three or four separate tickets because none of the tools know about each other. our vuln management process has turned into manual dedup work every week.

Is anyone running something that sits above the individual scanners and correlates findings automatically, or is this just the cost of running a multi-tool stack?
