This article takes an honest look at the features of HUMAN Security.
Since you're on the cside website, we acknowledge our bias. That said, we've built our case honestly and based our analysis on publicly available information, industry information, and our own or our customers' experiences.

| Criteria | cside | Human Security | Why It Matters | What the Consequences Are |
|---|---|---|---|---|
| Approaches used | Script-based monitoring + server-side analysis | JS-Based Detection | ||
| Real-time Protection | Full support |
Full support |
Attacks can occur between scans or in the excluded data when sampled | Delayed detection = active data breaches |
| Full Payload Analysis | Full support |
No support |
Ensures deep visibility into malicious behaviors within script code itself | Threats go unnoticed unless the source is known on a threat feed |
| Dynamic Threat Detection | Full support |
Full support |
Identifies attacks that change based on user, time, or location | Missed detection of targeted attacks |
| DOM-Level Threat Detection | Full support |
Full support |
Tracks changes to the DOM and observes how scripts behave during runtime | Unable to identify sophisticated DOM-based attacks |
| 100% Historical Tracking & Forensics | Full support |
No support |
Needed for incident response, auditing, and compliance | Needed for incident response, auditing, and compliance |
| Bypass Protection | Full support |
No support |
Stops attackers from circumventing controls via DOM obfuscation or evasion | Stealthy threats continue undetected |
| Certainty the Script Seen by User is Monitored | Full support |
No support |
Aligns analysis with what actually executes in the browser | Gaps between what's reviewed and what's actually executed |
| AI-driven Script Analysis | Full support |
No support |
Detects novel or evolving threats through behavior modeling | Reliance on manual updates, threat feeds or rules = slow and error-prone detection |
| QSA validated PCI dash | Full support |
No support |
The most reliable way to ensure a solution is PCI compliant is to conduct a thorough audit by an independent QSA | Without QSA validation, you rely entirely on marketing claims, which could result in failing an audit |
| SOC 2 Type II | Full support |
Full support |
Shows consistent operational security controls over time | Lacks verified security control validation, making it a risky vendor |
| PCI specific UI | Full support |
No support |
An easy interface for quick script review and justification via one click or AI automation | Mundane tasks and manual research on what all the scripts do, which takes hours or days |
| Ticketing Integrations (Linear, Jira) | Full support (Both Linear and Jira) |
No support |
Native integrations with developer ticketing tools allow security alerts to flow directly into existing workflows | Without native ticketing integrations, teams must manually create tickets for security findings, slowing response times |
What is HUMAN Security Client-side Defense?
HUMAN Security started in the bots detection space, and are well known for creating very sophisticated and lauded tools to tackle those issues. They've since expanded and offer products in client-side and other spaces.
HUMAN Security announced a merger with PerimeterX in July of 2022. They were then backed by a $100 million debt facility from Blackstone Credit, a Private Equity firm.
Client-side Defense is part of Application Protection, a suite of solutions purpose-built to secure web and mobile applications from a range of cyberthreats. Pricing is not publicly available, and you need to be an existing Human Security customer in order to use Client-side Defense
How HUMAN Security Client-side Defense works
HUMAN's Client-Side Defense works by embedding a JavaScript sensor directly into the website. This sensor runs in real user browsers and collects telemetry about all scripts executing on the page. It observes what scripts are loaded, what DOM elements they interact with, whether they access localStorage or cookies, and what outbound network connections they attempt to make.
While the script itself doesn't need to change frequently, your site updates makes managing this sensor and ensuring it stays current across environments a tad cumbersome.
Because it relies on JavaScript embedded in the page, it can only act after the browser has begun rendering content. There is a window of exposure before malicious scripts are caught or blocked.
This approach can prevent known patterns of attacks, but new attacks will be hardly impossible to prevent unless previously set up.
How cside goes further
HUMAN Security's Client-Side Defense monitors scripts after they've already been delivered to the browser. By the time HUMAN flags something suspicious, the malicious code has already had a chance to run. cside blocks scripts before they reach the browser.
HUMAN's strength is bot detection, and their client-side product extends that philosophy into script monitoring. But client-side security is a different problem. Attackers who inject skimmers into third-party scripts aren't bots. They're compromising supply chains. Detecting behavioral anomalies after delivery leaves a window where data can be exfiltrated in milliseconds.
cside works differently. We analyze scripts on our own infrastructure and inspect payloads before they're served. When we identify a threat, we block it at the network level. The malicious code never touches the user's browser.
For incident response, HUMAN provides behavioral monitoring logs. cside provides the actual attack code: the full payload that was blocked, preserved in an immutable archive. When your security team needs to understand what an attacker was trying to do, the evidence is there.
cside also integrates directly with Linear and Jira, so script security findings flow into your development team's existing workflows without manual ticket creation.
