What is cside?
Effectively tracking third-party scripts removes ambiguity, guaranteeing that you remain informed about what is sent to your users' browsers. The uncontrolled existence of these scripts within users' browsers can lead to major complications when issues arise, resulting in negative publicity, possible legal repercussions, and claims for damages due to security violations. Organizations that manage cardholder information must adhere to PCI DSS 4.0 requirements, specifically sections 6.4.3 and 11.6.1, which mandate the implementation of tamper-detection mechanisms by March 31, 2025, to avert attacks by alerting relevant parties of unauthorized changes to HTTP headers and payment details. c/side is distinguished as the only fully autonomous detection system focused on assessing third-party scripts, moving past a mere reliance on threat intelligence feeds or easily circumvented detection methods. Utilizing historical data and advanced artificial intelligence, c/side thoroughly evaluates the payloads and behaviors of scripts, taking a proactive approach to counter new threats. Our ongoing surveillance of numerous websites enables us to remain ahead of emerging attack methods, as we analyze all scripts to improve and strengthen our detection systems continually. This all-encompassing strategy not only protects your digital landscape but also cultivates increased assurance in the security of third-party integrations, fostering a safer online experience for users. Ultimately, embracing such robust monitoring practices can significantly enhance both the performance and security of web applications.

The cside platform features a specialized PCI DSS dashboard that provides clear insights into the requirements of 6.4.3 and 11.6.1.
Client-Side Protection Platform
Achieving complete session coverage, our system employs DOM-level comparison and detects threats based on specific conditions such as geographic location, time, or user grouping. The client-side component intercepts every request made to third-party sources, retrieves the corresponding JavaScript, and analyzes it in real-time. This proactive approach ensures that any harmful code is prevented from executing within the browser environment.
Bot Detection and Mitigation Software
cside is an innovative client-side security platform engineered to shield organizations from the escalating risks associated with browser-targeted attacks. In contrast to conventional security measures that depend primarily on threat intelligence feeds, cside utilizes an independent detection mechanism that leverages historical data and artificial intelligence to scrutinize the actions of third-party scripts. This forward-thinking strategy enables cside to detect and mitigate potential threats before they can impact users, delivering strong protection against zero-day exploits and supply chain compromises. Featuring a distinctive multi-layered defense system, cside provides exceptional security for client-side applications, making it an indispensable resource for any organization aiming to protect its online assets.
Artificial Intelligence Software
The cside AI system identified that the altered script demonstrated characteristics typical of keyloggers, resulting in it being marked as harmful. Users have the option to examine the script and, if warranted, prevent access by blocking the associated hash values.
AI Security Software
The detection system operates on an open-source large language model that functions exclusively within a self-managed setting.

Insane quality
Date: Apr 01 2025SummaryReally cool product with a young team that jumped on a few calls when we wanted extra information or had questions. Recommended!
PositiveWe needed a product like this for our PCI compliance (now needed for client-side monitoring and stuff). We found they had a free tier and after trying it and talking to their team we pulled the trigger. Super easy installation, dashboard looks perfect and just works. Pretty happy customer thus far!
NegativeThe free tier puts you on a waitlist. Our access got granted within the hour but would be nice if you have immediate access. Probably for quality control so I understand.

Critical visibility for our front-end security
Date: Jul 24 2025Summaryc/side has quickly become essential for our security and engineering teams. The visibility it gives us into third-party scripts is something we didn’t realize we were missing until we had it. The team behind it clearly knows the space and has been helpful anytime we had questions. Highly recommend, especially for teams navigating PCI compliance or looking to tighten up front-end security.
Positivec/side gives us real-time monitoring and forensic-level insight into third-party scripts, something we didn’t have before. It’s been a game changer for our security posture and compliance planning. The detection engine is smart, autonomous, and doesn’t require constant tuning or manual rule updates. We also saw slight performance improvements on script load times, which was an unexpected bonus
NegativeThe platform leans technical, which is fine for our team, but some views took a bit of getting used to

I feel safe!
Date: Jul 24 2025SummaryAt first, I was worried that running everything through a proxy might slow things down or break something, but honestly, performance hasn’t taken a hit at all—in fact, some things actually load faster. What really stood out was how much safer we felt once it was up and running—we could finally see what was changing on our site, block risky behavior, and stay compliant without having to micromanage every vendor. It’s one of those tools that gives you peace of mind in the background while letting you stay focused on building.
PositiveI think that the compliance tools for regulations are very well integrated, and the dashboard shows script changes with helpful AI explanations and options. I also appreciate the responsive support and seamless Slack/Teams alerts, plus easy setup which did not take long.
NegativeThe only con I would say is that it's hard to understand the dashboard at first, if you are non technical.
