Some big differences:

- Matano has realtime Python + SQL detections as code with advanced correlation support. Chronicle uses inflexible YARA-like detection rules iirc

- Matano supports Sigma detections by automatically transpiling them to the Python detection format

- Matano has an OSS Vendor Agnostic Security Data Lake and can work with multiple clouds / let's you bring your own query engine (Snowflake, Spark, Athena, BigQuery Omni). Chronicle is a proprietary SIEM that uses BigQuery under the hood and cannot be used with other tooling.

There are no limits on data retention or ingestion with Matano, it's your S3 bucket and the compute scales horizontally.

Thanks for the response. Chronice uses Yara-l and bigquery uses sql on steroids. Both are difficult to start working with them. I would want someone that has never even looked at python code to be able to query the data. Having a different query langauge than detection language is also a big problem (e.g.graylog). I will keep an open mind, I prefer python but it is not ideal for getting a wider audience (general IT staff) to use it. Junior staff prefer chronicle over splunk because they can put in an IP or domain and just get results. Now ask them to learn python and you have a revolt.

I looked at your sample detection on the home page. This is have for me but I can't get others to use it. I promise you, doing a little market research on thid outside of the tech bubble will save you a lot of money and resources.

Long term, I believe Python (along with good ol' SQL for correlation) is the best language to model the kind of attacker behaviours companies are dealing with in the cloud and a lot of the difficulties with it are not inherent but around tooling. For example, in our cloud offering we plan on building abstractions that let you search for an IP or domain and get results with a click of a button as well the ability to automatically import Sigma rules and test Python logic directly with an instant feedback loop of a "low-code" workflow.

Currently we focus on more modern companies with smaller teams that have engineers that can write Python detections and actually prefer it over a custom DSL that needs to be learned and has restrictions.

Keep in mind there are more people in general that know Python than are trained in a vendor-specfic DSL so perhaps long term the role of a security analyst will evolve to overlap with that of an engineer. We are already seeing more and more roles require basic proficiency in Python as attacks on the cloud become increasingly complex :)

Ok, so importing sigma rules is the easy part, it takes on average 2-3 hours of tuning a sigma imported rule to get it to where it is usable in a large environment where you have all sorts of false positives. The language in question should not me making a fuss about indentation or importing the right module. You never (to my knowledge) need loops, classes,etc... Python is great just not purpose built for this use case. Most companies, even fortune 50 companies can't get many people in their security team who know or are willing to learn python well. You need someone to write/maintain it, someome to review it and the people responding to detections would want to read it and understand it. I am not saying python is difficult, just that you have to take the time to learn it. Detection engineering is all about matching strings and numbers and analyzing or making decisions on them. You have to encode/decode things in python, deal with all kinds of exceptions, it is very involved compared to the alternatives like eql,spl,yara-l,etc... But them again, maybe your customers who want to run their own siem datalake in the cloud might also have armies of python coders. But generally speaking, it is rare (but it happens) to find people interested in learning python but also doing boring blue team work. I would love python so long as I don't have to deal with newer python versions requiring refactoring rules.

Fair enough, honestly, if your focus is silicon valley Python is great. You will just get a reputation about what your product demands of users if you ever want to branch out. The only time I have ever done a coding interview wss with a statup like typical YC funded type company. I am just warning you the world is different outside the bubble. I would want to recommend your product and I will probably mention it to others but it looks like you know what you want.

Attacks on the cloud are not that complex but python does not make the job easier just more complicated. And I spend at least 10-15% of my time writing Python so I am not hating on it.

The golden standard is splunk. Nothing, I mean absolutley no technology exists that even comes close to splunk. Not by miles. Not any DSL or programming language. Do you know why CS Falcon is the #1 EDR, similary all alone at the top? Splunk!

Even people that leave splunk to start a competitor like Graylog and Cribl can't get close.

A detection engineer is a data analyst (not a scientist or researcher) that understands threat actor's TTPs and the enterprise they are defending well. I wish I wasn't typing on mobile so I can give you an example of what I mean. None of the sigma rules out there come close to the complexity of some the rules I have seen or written. Primarily, I need to piece together conditions and analysis functions rapidly to generate some content and ideally be able to visualise it. It doesn't matter how good you are with a language, can you work with it easily and rapidly enough to analyze the data and make sense of it? Maybe you can get python to do this, I haven't tried. But you are not going to compete with Splunk or Kusto like that. The workflow is more akin to shell scripting than coding where you cam easily pipe and redirect IO.

E.g.: "Find GCP service account authentication where subsequently the account was used to perform operations it rarely performs and from IP addresses located in countries from which there has not been a recent login for that project in the last 60 days"

I am just giving you an example of what a detection engineer might want to do, especially if they've been spoiled by something like Kusto or Splunk SPL. That's the future not simple matches.

The role of a security analyst and engineer already overlap, modern security teams have a lot of cross functionality where everyone in part is involved and embedded with other teams that have the same security objective (detect threat actors in this case).

Just to show you the state of things. I can't get a team solely dedicated to security automation to write one simple python script to solve humongoud problem that we have. We spent over a year arguing and battling over the solution. The hangup was they would be responsible for maintaining it, so instead they wanted an outside vendor to do it.

At a completely different company, I wrote a small python script to make my life analyzing certain incidents easier and that started a territorial battle.

What you consider a simple python script requires consultants and many meetings amd reviews and approvals at bigcompanies and they're constantly worried the guy who wrote the script can't be replaces easily. I am telling you all this so you understand how people making purchasing decisions think: they are very much on the buy side of things than build once a company gets to a certain size when their main business is not technology services.

So I hope you also think about offering managed detection/maintenace services (kind of like where socprime is going) in the long term.

Finally, I think your strategy is to have an exit/ipo in a few years and if you don't see long past that, I have no doubt you will succeed. And I am very happy to hear about another player in this field. I have even pitched building an in house datalake solution similar to this except with tiered storage where you drop/enrich/summarize data at each tier (you need lots of data immediately but less details and more analysis of that data at each tier).

I wish you the best of luck!

Thank you for typing up a long detailed response. I think a lot of the points and concerns you bring up are valid, and we are mostly agreed upon.

In Matano however, we see Python as a viable component in security operations for narrowly tracking atomic signals while the language for writing detections and hunting threats will be SQL, which works perfectly well for use cases like the detection example you provided, albeit verbose. We have thought of also building a transpiler that would let analysts actually use the succinct syntax of SPL and compile that to SQL under the hood. This could be a great way to get adoption in companies where using Python would be difficult.

If you are interested, I would love to find some time to chat and share thoughts. Can you email me at shaeq at matano dot dev?

[_8j50]

Thanks for the well thought out response. I hope Matano succeeds. I can't email you since my hn presence isn't public/social but I might be involved in evaluating your product some day soon and would chat and share thoughts with your folks then.

Do you have contact info to consult about this stuff in a few months? Building something adjacent and analyst usability is top of mind.

I started my career doing detections (Snort / ClamAV) but have been out of the loop doing development for a while. A fresh perspective would be helpful.

[_8j50]

Sorry,can't consult but if I see a post from you asking about this, I will be sure to respond/discuss that in detail.
