About CybersecurityNews.us
CybersecurityNews.us tells you when something affects the technology you use.
Follow the vendors, products and topics you care about on cybersecuritynews.us. This extension shows the vulnerabilities and threats that match them, newest first, right in your toolbar, with why each one matched ("Involves Microsoft Exchange, a product you follow").
• Alerts for urgent issues: actively exploited, critical, or on CISA's Known Exploited Vulnerabilities list. Critical alerts are free on every plan.
• A badge with the number of new matches since you last looked.
• Search all of CybersecurityNews.us from the popup: CVE IDs, vendor and product names, or phrases like "exploited this week".
• One click to the full story: what happened, why it matters and what to do, with every source linked.
• Your settings follow you: change what you follow on the website and the extension updates.
Sign in with a free CybersecurityNews.us account. Subscribers also get high and all-match alerts, quiet hours and larger profiles.
Privacy: the extension signs in with a link we email you, which works only for this extension on this browser. It downloads your matches from cybersecuritynews.us and does not read your browsing, the pages you visit, or other sites. You can sign it out any time from your account on the website.
