Show IH: Crimson Aegis - Data loss prevention integration for Slack

7

Hi my fellow indie hackers!

I just launched my first paid SaaS, https://crimsonaegis.com. Crimson Aegis is a data loss prevention (DLP) integration for Slack. It checks your Slack messages to make sure you aren't posting sensitive information like credit card number and social security numbers and gives the option to remove messages.

About the stack:

  • 100% Elixir with Phoenix

  • Postgres for DB

  • Stripe for payments

  • Hosted on Google Compute Engine

  • SendGrid for transactional emails

  • Sentry for error reporting

Any feedback is greatly appreciated!

    I love that it is an elixir app (best language ever). and the landing page design is gorgeous.

    on the other side it would be super interesting to hear the story behind the product. 100$/mo sounds like you are solving either a super hard problem (don't think so since you can get pretty far with regex for identifying credit card numbers and social security numbers) or you are solving a pretty pressing problem for companies.

    How did you validate your idea? what made you choose this price point?

    1. 1

      The idea came from a need at one of my previous jobs where there was apprehension for adopting Slack because of sensitive data being in messages.

      The pricing is based off who I'm trying to target. I would think medium-sized business who might talk to customers inside their Slack would be my biggest audience (but I don't know yet). For Slack, you have to have Slack Enterprise Grid to get DLP provided by them but that probably would cost a pretty penny (they have no pricing listed for that tier).

      As for the problem, regexes can get you pretty far but I also support file and image inspection and much more than just SSNs and credit card numbers.

        so you can see whether there is sensitive information in a file or an image? if yes, that would be super cool. You might want to add a list of things you can detect on your landing page

        1. 3

          Yes. I'll make sure to make that more apparent.

    Definitely interesting use-case - never really thought about it but makes perfect sense :)

    Nicely designed page - although not sure if there is an image (maybe Slack logo?) missing here or...? I'm on Mac/Firefox.

    Props for the GIF showing the product on the top - simple & effective 👌

    Also what @rasmus1610 said - I would definitely expand onto this bullet-point File Inspection as it seems pretty interesting. Out of curiousity - how it works? I guess .txt files are easy, but on images it does the OCR or...?

      A Slack logo is supposed to be there. I'll investigate it on FF.

      Text files are treated like regular text messages after the file is read. For images, OCR is being used for inspection.

    Second the kudos for the landing page. Looks really polished. Did you design it yourself?

    1. 1

      Thanks! I sure did!

        Wow, so you're an Elixir hacker and a great designer to boot! 👏👏
