It is 2025, and most people still buy computers that are just as insecure as they were ten years ago. Your new laptop comes out of the box, you switch it on \u2013 and from the first second on the Internet, your Internet provider knows exactly which websites you visit. Not only that: this information is transmitted unencrypted, is vulnerable to manipulation, and opens the door for malware.<\/p>\n\n\n\n

At Lumi-Systems, we do things differently.<\/strong><\/p>\n\n\n\n

The invisible protective shield: What Quad9 DNS means for you<\/h2>\n\n\n\n

Every notebook that leaves our warehouse in Vienna is already equipped with a security configuration that normally only IT professionals give their own systems: Quad9 DNS with DNS-over-TLS and DNSSEC<\/strong>.<\/p>\n\n\n\n

What sounds like technical jargon at first means something very concrete for you as a user: You get your first protective wall against digital threats from us free of charge \u2013 and it works from the first second.<\/strong><\/p>\n\n\n\n

What makes Quad9 DNS so special?<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Quad9 <\/a>is not an ordinary DNS service. While most people use their Internet provider's DNS servers (often without knowing it), we deliberately chose an alternative that puts your security and privacy first.<\/p>\n\n\n\n

Here are the concrete benefits you use every day:<\/strong><\/p>\n\n\n\n

\ud83d\udee1\ufe0f 1. Automatic malware protection \u2013 without additional software<\/h4>\n\n\n\n

Quad9 automatically blocks access to known malware domains before you can even reach a dangerous website. The special thing: This blocking happens at the DNS level \u2013 before your browser even contacts the website.<\/p>\n\n\n\n

What that means for you:<\/strong> You don't have to buy or configure additional security software. The protection is simply there, in the background, 24\/7.<\/p>\n\n\n\n

A practical example:<\/strong> Phishing emails contain links to fake banking websites. Even if you click such a link, the connection is blocked by Quad9 before the fake page loads. You see an error message instead of a deceptively real fake page.<\/p>\n\n\n\n

\ud83d\udd12 2. Encrypted DNS requests: Your Internet provider sees less<\/h4>\n\n\n\n

Normally, your Internet provider can see every website you visit \u2013 even if the website itself is encrypted (HTTPS). Why? Because the DNS request is sent unencrypted.<\/p>\n\n\n\n

We enable on all Lumi-Systems notebooks DNS-over-TLS (DoT)<\/strong>. This means: Your DNS requests are transmitted encrypted over port 853. Your internet provider only sees encrypted traffic, not which websites you visit.<\/p>\n\n\n\n

What that means for you:<\/strong> More privacy. Period. Your browsing behavior remains your business \u2013 not your internet provider's.<\/p>\n\n\n\n

\u2705 3. DNSSEC: Protection against manipulation<\/h4>\n\n\n\n

DNSSEC (Domain Name System Security Extensions) ensures that the DNS responses you receive are authentic and were not manipulated on the way to you.<\/p>\n\n\n\n

What that means for you:<\/strong> Protection against DNS hijacking and cache poisoning attacks. When you type \u201ebank.at\u201c into your browser, you actually end up at bank.at \u2013 and not at a fake page from an attacker.<\/p>\n\n\n\n

\ud83c\udde8\ud83c\udded 4. Privacy by Design: No logs, no trackers<\/h4>\n\n\n\n

Quad9 is a non-profit organization based in Switzerland and is subject to strict European data protection laws. Unlike many other DNS providers:<\/p>\n\n\n\n
