Headless technology
and Grey Box

Headless and Grey Box

The Headless technology is one of the main features that you can find in the current cybersecurity solutions. Thanks to this technology, the website or web application is 100% mapped, including for the dynamic content. They refer to all the user-adjustable and variable elements that you can find within the code, like Javascript, CSS, or even pictures.

Usually, this kind of content cannot be analyzed by a robot because it is bound to a graphic interface.

Just like all the modules from the HTTPCS suite, Integrity has a Headless navigation that can detect the occurrence of fraudulent changes on the whole website.

Just like Change Tower, the technology used by HTTPCS goes beyond any regular solution and can map the external sources mentioned above.

The two solutions can check the content availability through an authentication, which is called a Grey Box test.

ChangeTower provides, just like many integrity checkers, the management of dynamic content (Javascript). It also enables the management of authenticated content, i.e. Grey Box.

Scanner frequency

Scanner frequency

The frequency of an integrity checker scanner is the time between two scans of a web application or a website. Therefore, the shorter that time is, the easier it will be to intervene in case of any fraudulent change.

The Integrity by HTTPCS solution delivers an unbeatable performance with its capacity to fully crawl in real time. This asset has the advantage of instantly detecting a change and taking appropriate measures for getting back to normal. With its 100% mapping, the number of pages to analyze is unlimited. By contrast, the Change Tower integrity monitoring is limited to 1000 URL per day, with a check at least every 100 seconds.

Scanner frequency
The web application or website is entirely checked in real time, without any URL limitation. This advantage makes the scanner very responsive in case of any unwanted change on the website.

Scanner frequency
With a 1000-scan limitation per day and a monitoring frequency of 100 seconds, the Change Tower scanner is less efficient than the HTTPCS one.



In case of any acknowledged fraudulent change, the crisis management teams must be warned as soon as possible. One of the most popular means of contact is the email, which is economic and efficient when the employees are working on their computer.

On the other hand, the SMS alert can be favored if the working teams are away because it’s the only way to let them know about an anomaly.

The difference between two solutions regarding the notification system won’t be the means of contact provided, but the number of recipients authorized to receive these alerts.

Integrity by HTTPCS has the advantage of sending notifications (by text, email and API) to an unlimited number of recipients. The alerts are sent without any limitation.

As for Change Tower, the service only provides email alerts. Even if the number of notifications is unlimited, only a small number of users (from 1 to 20, depending on the plan subscribed) will benefit from the notification system. You can also add users who will receive the alerts, but they won’t have access to the integrity checker. This implementation implies an additional cost of 8 € / month per user.

Text, email and API alerts are unlimited. The number of recipients is also unlimited.

Change Tower unlimited alerts are sent by email. The number of recipients is limited and adding a user will lead to additional costs.

Viewing and data storage

Viewing and data retention

One of the features of an integrity checker is to let the user view the potential fraudulent change and the impact caused on the website or web application.

Just like Change Tower, Integrity by HTTPCS lets you see the changes, thanks to a simple and very efficient “before/after” system. Therefore, you don’t need any technical knowledge to understand the causes and the consequences of a detected change.

Data retention refers to the period at which the user of the integrity checker can access the history of the detected changes. This feature is very useful because it gives the possibility for the company to perform statistical studies on its website.

Integrity by HTTPCS stores its users’ data during the whole duration of the subscription, while Change Tower stores them for a 3-month period (this duration can be extended by paying additional costs).

In case of cancellation of the Integrity offer, the data will still be stored for one year, for an efficient and lossless migration.

Data retention is unlimited, with a viewing of the “before/after” changes.

The significant specificities of HTTPCS Integrity are the external sources check on a website and its complementarity with other modules from the HTTPCS suite.

The HTTPCS engineers considered that the fraudulent changes made on a website would go unnoticed when they came from external sources (Javascript, CSS, pictures…). Therefore, HTTPCS developed a technology that can check for external sources content on a website or a web application.

In addition, Integrity works in a complementary way within the HTTPCS cybersecurity suite:

  • The Monitoring by HTTPCS tool monitors an application availability and alerts the user at any time in case of a downtime.
  • The Security scanner detects every flaw or vulnerability on a website or web application
  • The CyberVigilance monitoring solution constantly analyzes the web, deepweb and darknet to detect threats by hackers that could affect your company

The advantage of the Change Tower offer is its competitor monitoring feature, that monitors websites and forums to find information about your company. Therefore, every time your company’s name is mentioned anywhere (limited to 1000 checks per day) and that the information is considered as useful, your company is alerted right away.

The specificity of Integrity by HTTPCS is its capacity to monitor any changes from external sources. The solution blends in perfectly with the HTTPCS suite composed of 3 additional modules (Security, Monitoring and CyberVigilance).

The Change Tower competitor monitoring tool can set up monitors on strategic websites or forums for your company.
