vsb.org is the online home of the Virginia State Bar, the state agency that regulates lawyers in Virginia. If you're here to pay dues, check MCLE compliance, or look up an attorney, you're on the right site. The domain has been active since 1996, and its web archive goes back nearly as far — that kind of continuous history is nearly impossible to fake.
Security is solid: the site uses modern encryption and sets browser protections to block common attacks. It also has a valid privacy policy and terms of service, which is appropriate for a site that handles member logins. The only oddity we found was a redirect loop when trying to access some internal pages, but that appears to be related to the member portal's login system, not a sign of anything malicious.
For a state bar site, the key thing is to make sure you're on the real domain when entering sensitive information. vsb.org is the genuine article. If you see a different domain asking for your bar number or payment, that's when you should be cautious. But here, the signals are overwhelmingly positive.
