r/MSSP

Hi everyone - I’m an investor researching the MSP space, particularly the newer generation of providers that acquire smaller MSPs and then use AI to streamline operations.

I’d really value your perspective:

> What has your experience with MSPs been so far?
> How do you feel about providers increasingly automating IT and security workflows?

>Would you be comfortable entrusting your IT/security to a more AI-driven MSP?

> Any insights, examples, or concerns would be incredibly helpful.

I’m evaluating modern SIEM / XDR / SecOps platforms and would appreciate input from people who have gone through similar selection or migration projects.

Context:
We have a relatively small security team - essentially one person responsible for security operations, but the environment is not small: several thousand servers, around 1.5k users, hybrid identity with Microsoft Entra ID and on-prem Active Directory, and a mixed OS estate that is currently about 40% Windows and 60% Linux, with more Linux migration planned.

What I’m looking for is not just a log storage/search platform, but a SIEM/SecOps solution that can realistically work for a very lean team.

Key requirements:

* Strong integrations with Microsoft identity, AD, Windows, Linux, network/security tools, cloud services, and custom applications.
* Flexible detection / alerting language, similar in spirit to Splunk SPL, KQL, YARA-L, Python-based detections, etc.
* Good support for custom log ingestion, because we have internal applications and products that we will need to integrate from scratch.
* Vendor-maintained detection content, not just a marketplace of rules we have to fully own ourselves.
* Strong ML/UEBA/anomaly detection capabilities.
* AI-assisted investigation would be a plus, especially if it can explain context, summarize incidents, suggest next steps, or help build detections - but this is not the main deciding factor.
* Ability to reduce operational overhead: tuning, rule updates, parsing, correlation, triage, and detection lifecycle should be as delegated as possible to the vendor or an MSSP/MDR partner.

As a reference point, we previously used Darktrace Network. I liked the idea that many detections/models were maintained by the vendor, were relatively flexible, and heavily ML-driven. I’m looking for something with a similar operational philosophy, but in the SIEM/SecOps space.

Platforms I’m considering include Microsoft Sentinel (good fit for us as I said we have Microsoft ecosystem), Google Security Operations (ex-Chronicle), PaloAlto (XDR, XSIAM), CrowdStrike (XDR, Next-Gen SIEM), any other modern SIEM/XDR options.

**The main question**:
For a one-person security team managing a large hybrid environment, which SIEM/XDR/SecOps platform would you recommend?

***DISCLAIMER: I understand that in our context, full outsource/MSSP/MDR are the best options, but we decided to start without them for now, with the intention of transitioning to MSSP/MDR later.***

I’d especially appreciate feedback on:

* real operational effort after deployment,
* quality of out-of-the-box detections,
* custom log onboarding,
* detection language flexibility,
* false-positive tuning,
* Linux visibility,
* Microsoft identity integration,
* vendor support quality,
* pricing predictability at scale.

I feel like browser security is a blind spot that gets ignored in a lot of environments.

While looking into solutions, I came across things like LayerX, Keep Aware, and a few other vendors. At the moment, I don’t see anything on LayerX’s site about an MSSP-supported mode, and ideally we’d want to roll this out as a paid service.

Would appreciate if anyone can share real-world experience deploying LayerX—especially from an MSSP angle—or if there are other tools that fit better for that model. I’d prefer not to go down the route of heavier enterprise browser approaches like Island.

I’m looking to acquire an MSP. My background is on security compliance (12+ years). A niche MSP like dental offices seems attractive in which a current MSP might not be offering HIPAA compliance services.
My question (or doubt) is. Maybe those dental offices are too small, they don’t care, they just sign any BAA template they see, and the market is not there?

Hi all,
Looking for a solid multi-tenant 3rd party CSPM platform. We don't want to use Microsoft as our SOC will use it as much as the MSP, and we don't want to access their Microsoft tenant.

Any recommendations? Does anyone have practical experience with one?

Hi all. We are MSSP running Sentinel for around 40 tenants now , the business is growing but already the simple operations is getting painful.

Lighthouse for delegated access , WOrkspace Manager for pushing rules and workbooks. WM updates is slow and sometimes not reflecting , my colleague opened support cases a few times. Cross workspace() work but performance variables. Updating one rule across the tenants when MS changes a template is basically someones entire job.

Per customer tunings , their watchlists , exclusions, also hard to keep separate from the baseline we push.

Anyone running 50-80 tenants in Lighthouse smoothly? Or is just pain at that scale?

Workspace Manager in production or you rolled your own with Bicep , Terraform , Sentinel as COde?

Analysts in Defender XDR unified portal or jumping per-tenant?

And same playbook copied 40 times with small differences, how you handle that?

A huge part of the queue ends up being noise, but analysts still have to spend time reviewing and triaging it. Over time, that affects everything: response speed, investigation quality and overall efficiency.

What makes it harder is that once the volume gets high enough, teams naturally start moving faster just to keep up. And that’s where important detections can get buried or downgraded.

What has made the biggest difference for your team when it comes to reducing unnecessary alerts?

Have any of you used patchmypc at any scale?
The pricing is very hard to beat, but I'm hesitant to use something I haven't heard of compared to tools like Automox and ManageEngine.
If you have used it at scale, I would very much like to hear your experience.

Use case: managed patch SKU for clients as a standalone product, not part of a larger stack.
Business: MSSP for MSPs working behind the scenes. We are usually full stack but want a standlone patch offering.
