Why we think so

postfinance.ch is the official site of PostFinance, a large Swiss financial institution with over 4 million monthly visits. It offers banking and payment services mainly in Switzerland, ranking #9,685 globally and #54 nationally in Switzerland. The site uses reputable technologies including Adobe Experience Manager and CloudFlare CDN, supports multiple languages, and has a valid SSL certificate issued by SwissSign. Contact details and official social media profiles are publicly available, supporting trust. However, online reviews reveal customer dissatisfaction with fees, service quality, and its mobile banking app. Scam activities frequently involve fake PostFinance sites and phishing, but these impersonate the brand rather than the official domain itself. PostFinance is involved in legal and regulatory disputes typical for a state-owned bank, but no evidence suggests the domain or bank is inherently unsafe or fraudulent.
