AI powered compliance

Excited to announce cside AI powered compliance engine.

Compliance requirements like PCI DSS require merchants to maintain technical or business justifications for scripts to be on a given page. This can be a difficult task to do manually but, by understanding the script code and gaining further usage context AI can do a perfect job! Therefore we are excited to share our range of AI compliance features.

With our AI script justifications, one click solves the requirement.

And we are not taking any risks. We do not leak any sensitive information to any 3rd party as we are hosting a model ourself. We do not talk to a 3rd party API, there is no risk of data leakage.

With our AI features, we aim to make compliance simpler.
With our AI features, we make life harder for bad actors to fly below the radar.
With our AI features, we make it easier to understand what the scripts on your website are doing.

We're solving client-side security.

cside becomes cside and we're on .com!

Excited to share a very gentle rebrand to cside (at least in copy). Legacy search algorithms struggle to understand special characters and this became an increasingly silly problem. So from now on, it is cside. With the new brand, we're also pushing a new website, cside.com. Our new website unveils the long ongoing effort of cside’s expansion to other client-side security solvable problems. To begin, Chargeback fraud evidence for Compelling Evidence v3, detecting fraudulent applicants as they fill out the job form and various privacy and compliance use-cases.

Channel partner program

We’re proud to announce the launch of our Partner Program. This initiative equips our partners with the tools, resources, and flexible business models they need to help their clients stay safe from client-side attacks.

Through our unified dashboard, partners can efficiently manage all their client projects while offering a revenue-generating solution that not only strengthens website security but also delivers measurable performance gains.

Offering a flexible 3 tier identity access model.

  1. Organizations contain billing information and some top level platform controls. An organization contains one or more teams.
  2. Teams are fully isolated from one another. End customer can be invited to this team. The team contains the various domains of a customer.
  3. Domain level contains all the client-side dashboard and intelligence.

The cside partner program was built with a range of indirect sales channels in mind:

  1. Service integrators and PCI consultants.
  2. Web development agencies.
  3. Full integrations into PaaS or lowcode hosted site platforms.

Introducing the cside sidebar

We were running out of space. With some more custom views and new products coming our way we needed to create a bigger playing field, so we're introducing a new dashboard layout.

The cside sidebar houses a new range of views and easier access to features you need more regularly.

JA4 TLD fingerprinting

We introduced per-connection features based on JA3/JA4 TLS fingerprinting. By computing the JA4 hash from the full TLS ClientHello (including cipher suites, extensions, ALPN, and elliptic curves), we can now detect VPN client software that attempts to masquerade as a standard web browser.

Launching the cside blog RSS feed

When we started cside, one of the core deliverables was to bring awareness to client-side executed attacks. Bad actors know you have a range of various tools for internal IT security, server-side security, network flow monitoring, static registry open source dependency monitoring, heck, we even pay for DLP repackaged, promising to prevent data leakage to LLMs...

But companies do not know how their site and their dependencies behave in the browser of their user. This blog constantly talks about attacks we find. Attacks that would not have been discovered if it wasn't for cside, its customer base, and the research we do.

So, to those who enjoy our content and wish to stay on top of our findings, we have now released an RSS feed (https://cside.com/blog/rss.xml).

Making it easier than ever for you to stay up to date on our content.
