Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on telefonserwis.pl and not a lookalike like t-elefonserwis.pl.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

Safety FAQ
Common questions about this site, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.

- telefonserwis.pl passed our automated security checks with a trust score of 93/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.
- Yes. telefonserwis.pl presents a valid TLSv1.3 certificate issued by Let's Encrypt · E7, expiring in 20 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.

- This is a permanent record of the scan run on June 29, 2026. The verdict and evidence above reflect that scan and do not change on their own. If circumstances around telefonserwis.pl have changed, MalwareTips staff can run a fresh scan, which re-runs every check from scratch and publishes an updated report.
