Description

Marchex is a call tracking and conversation intelligence platform that uses dynamic number insertion to attribute inbound phone calls to marketing campaigns, and analyzes call content with AI. calls.net is confirmed owned by Marchex, Inc. via WHOIS (registered 1998, managed by MarkMonitor).

AI Review

The scripts from marchex.com and its affiliated domain web-2-tel.com focus predominantly on detecting and processing phone numbers on web pages. They utilize various techniques, including regular expressions, to identify both visible and hidden telephone numbers, which raises significant privacy concerns due to the sensitive nature of the data involved. Key data elements collected include not only phone numbers but also session variables and metadata, which are sent to remote servers. The operational transparency for users regarding this data collection appears limited, leading to risks associated with unauthorized surveillance and potential data misuse, especially as the information can be directly tied to user sessions. Despite claims that these services enhance telephony capabilities and assist in fraud detection, the focus on extensive data collection within user interactions presents challenges. The reliance on third-party APIs can heighten supply chain vulnerabilities, requiring careful management of the data collected. The lack of recent alerts suggests that there are no current threats; however, ongoing monitoring of the scripts' data practices and user consent management is essential to mitigate risks related to privacy and compliance.

This domain is analyzed as part of cside's domain directory to identify third-party scripts and their purposes. The summary provides information about what services, tools, or scripts this domain hosts, helping website owners understand which third-party services are being loaded on their sites.

The risk score is calculated based on multiple security factors including SSL certificate validity, DNSSEC status, domain registration details, and historical security data. A higher score indicates lower risk, while a lower score suggests potential security concerns that should be investigated.

The SSL certificate information shows whether the domain uses HTTPS encryption, when the certificate was issued, when it expires, and who issued it. This helps verify the domain's security posture and identify potential certificate-related vulnerabilities that could affect your website's security.

Third-party script domains can be compromised or used maliciously. By monitoring domain information like registration details, SSL certificates, and DNS records, you can identify suspicious changes, expired certificates, or domains that may pose security risks to your website and users.

Domain information is regularly scanned and updated to provide the most current security intelligence. The last scanned timestamp shows when the most recent analysis was performed, ensuring you have up-to-date information about the domain's security status.

If you identify a high-risk domain loading scripts on your website, you should investigate why it's being used, verify its legitimacy, and consider removing or replacing it if it's not essential. Use cside's platform to monitor and block suspicious third-party scripts to protect your users from potential security threats.
