c/side Description
Monitoring third-party scripts effectively eliminates uncertainty, ensuring that you are always aware of what is being delivered to your users' browsers, while also enhancing script performance by up to 30%. The unchecked presence of these scripts in users' browsers can lead to significant issues when things go awry, resulting in adverse publicity, potential legal actions, and claims for damages stemming from security breaches. Compliance with PCI DSS 4.0, particularly sections 6.4.3 and 11.6.1, requires that organizations handling cardholder data implement tamper-detection measures by March 31, 2025, to help prevent attacks by notifying stakeholders of unauthorized modifications to HTTP headers and payment information. c/side stands out as the sole fully autonomous detection solution dedicated to evaluating third-party scripts, moving beyond reliance on merely threat feed intelligence or easily bypassed detections. By leveraging historical data and artificial intelligence, c/side meticulously analyzes the payloads and behaviors of scripts, ensuring a proactive stance against emerging threats. Our continuous monitoring of numerous sites allows us to stay ahead of new attack vectors, as we process all scripts to refine and enhance our detection capabilities. This comprehensive approach not only safeguards your digital environment but also instills greater confidence in the security of third-party integrations.

c/side Features and Options
Client-Side Protection Platform
Achieving complete session coverage, our solution employs DOM-level comparisons and conditional threat identification based on geographic location, time, and user demographics. The client-side component intercepts all third-party requests, retrieves the relevant JavaScript, and analyzes it instantaneously. This proactive approach ensures that any harmful code is prevented from being executed by the browser before it runs even a single line.
GDPR Compliance Software
The proxy and crawler systems solely retain the requester’s IP address for the purpose of incident analysis; this information is not sold or utilized for marketing purposes. All data from the proxy and crawler is securely maintained within c/side-managed clusters located in AWS.
PCI Compliance Software
With the capability of real-time payload examination, automated prevention measures, comprehensive storage of historical payloads, and reports that are prepared for auditing, which align precisely with the testing protocols outlined in PCI DSS 4.0.1.
Compliance Software
An independent evaluation by VikingCloud verifies that when set up correctly, both the hybrid proxy and crawler modes meet these standards by persistently hashing, analyzing, and blocking scripts in real-time when needed. The c/side platform features a specialized PCI DSS dashboard that specifically addresses the insights related to requirements 6.4.3 and 11.6.1.
IT Security Software
Combat threats like Magecart, formjacking, token hijacking, and cryptojacking effectively! By implementing a proxy-based framework, a proxy operates between the user’s browser and third-party scripts, enabling it to monitor the code retrieved by the browser. This client-side proxy ensures constant, comprehensive visibility and oversight of every third-party script running in the user's browser at all times, without relying on sampling techniques.
Artificial Intelligence Software
The c/side AI system identified that the altered script demonstrated characteristics of a keylogger, categorizing it as harmful. Users are then able to examine the script and, if needed, prevent access by blocking the associated hash values.
Website Security Software
VikingCloud reported that their c/side platform successfully detected and halted a third-party script to safeguard against data breaches.
Bot Detection and Mitigation Software
c/side is an innovative client-side security solution aimed at shielding digital enterprises from the increasing risks associated with browser-based threats. Unlike conventional security measures that depend primarily on threat intelligence feeds, c/side utilizes a fully autonomous detection mechanism that leverages historical data and artificial intelligence to scrutinize the behavior and payloads of third-party scripts. This forward-thinking strategy enables c/side to spot and neutralize potential dangers before they can affect your users, providing strong defense against zero-day exploits and supply chain vulnerabilities. Featuring a distinctive proxy solution, c/side delivers unmatched protection for client-side applications, making it an indispensable asset for organizations seeking to secure their online presence.
AI Security Software
The detection system operates on a publicly available large language model (LLM) that is fully contained within a privately managed infrastructure.

Gives us needed visibility into client-side activity Date: Jun 10 2025
Summary: Overall, c/side has been incredibly valuable for finally seeing what third-party scripts are doing on our site. This clear insight helps us catch problems and coordinate better. The interface could be more intuitive, but the visibility it provides is a huge win for our security.
Positive: It helps us understand what third-party scripts are actually doing on our site, which used to be pretty opaque. Instead of relying on assumptions or manual checks, we can now see script behavior clearly, which has helped us spot issues we wouldn’t have caught otherwise. It’s also been helpful when coordinating with teams during incidents.
Negative: Some parts of the interface aren’t immediately intuitive. It took a bit of trial and error to get familiar with the different views and how to filter the data effectively. Also, it would be helpful to have more built-in guidance or examples for interpreting script behavior.

Insane quality Date: Apr 01 2025
Summary: Really cool product with a young team that jumped on a few calls when we wanted extra information or had questions. Recommended!
Positive: We 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!
Negative: The 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.
