    Google Chrome Enterprise
    Chrome Enterprise strengthens overall computer security by integrating tightly with endpoint protection frameworks and leveraging browser-specific defenses. It isolates each tab to prevent lateral movement of malware and ensures that security patches are applied continuously with automatic updates. Features like Safe Browsing block access to known harmful sites, while sandboxing reduces the risk of drive-by infections. Chrome’s security model minimizes attack surfaces on endpoints and complements antivirus and firewall protections, making it a key component in securing corporate devices against sophisticated web-based threats. By providing layered security within the browser itself, Chrome Enterprise acts as the first line of defense against many cyberattacks. This reduces the burden on traditional security tools and improves overall system resilience.

    AntiBrowserSpy

    AntiBrowserSpy

    Abelssoft Ascora GmbH

    As soon as we surf the Internet we are being monitored and spied on. By means of cookies and tracking, the online services called up can automatically determine from which country a visitor comes, what operating system is used and which browser is used. Our Windows tool AntiBrowserSpy dries up the involuntary data flow and sets up a muzzle for the web browser. The browser cloak of invisibility of the tool prevents the browsers: Chrome, Firefox, Opera and Microsoft Edge, that the user is recognized based on his typical browser "fingerprint". A Google Analytics Blocker and a local browser cleaning (cache, cookies and history) complete the range of functions. In addition, the integrated BrowserCheck checks after each surfing session whether something has changed in the browser settings, for example, due to an update, and informs you immediately if there are any deviations.
