SafeToOpen Online Security: Seatbelt for your browser!

Protect employees against scams, viruses, and new phishing web pages with SafeToOpen.

What is a zero-day phishing website?

Zero-day (or never-before-seen) phishing website is a term that generally refers to a type of phishing attack in which a website is created specifically to steal money or sensitive information that is unknown to the cybersecurity vendors or communities, making it difficult to detect and prevent.

The SafeToOpen Online Security browser extension detects and protects against zero-day phishing websites in real-time. It prevents you from submitting your sensitive information and reports newly detected phishing links to other cybersecurity vendors to help protect others.

Why organizations need SafeToOpen Online Security?

  • Current cybersecurity tools such as anti-viruses, web proxies, and secure email gateways are unable to protect against new phishing web pages. Staff members may click on malicious links from their personal emails, social media, or text messages that are not monitored by the secure email gateway.
  • Employees may receive HTML phishing attachments, and no tools can effectively protect them.
  • Employees receive warnings once they have visited malicious web pages and report the links to your security team in a few seconds.
  • Staff members are prevented from submitting sensitive information to unsafe web pages.
SafeToOpen Layer Approach

Why on the browser?

Web browsers serve as gateways to the internet. If security tools and controls such as antivirus software, secure email gateways, web proxies, and browser-based protections fail to detect and prevent a new phishing attack, then victims may end up opening malicious web pages through their browsers.

This is the ideal location for SafeToOpen Online Security to examine the page's content and detect and safeguard staff members from unsafe web pages that other security tools have failed to identify.

SafeToOpen Online Security examines both the visual elements, such as images and logos, and the hidden elements, such as embedded JavaScript, of the page - much like a cybersecurity expert - and alerts the staff members if the web page poses a risk, and gives them peace of mind if it is safe.

Common online security software and cybersecurity tools often fail to protect against never before seen phishing web pages.

SafeToOpen Online Security protects from phishing HTML attachments

Video Description

HTML attachments in phishing emails often go unnoticed by email security products, allowing them to reach the recipient's inbox.

These attachments are used to redirect users to malicious websites, download files, or display phishing forms within the browser.

SafeToOpen Online Security quickly detects these phishing attempts through HTML attachments and informs staff members not to enter any sensitive information.

SafeToOpen Dashboard

What happens following detection?

After visiting an unsafe web page, we notify the visitors and your security team. An email alert is also sent with all the necessary information for the security analyst to investigate the incident to your security team and generate an incident in the SafeToOpen dashboard.

Security analysts review the findings and decide to either block or allow the URL for the entire organization with one click.
