If you've landed on risknarrative.atlassian.net, you're looking at a login page that's part of Atlassian's ecosystem. Atlassian is the company behind Jira, Confluence, and other popular tools, and they're a publicly traded company with a longstanding reputation. The subdomain itself is protected with modern encryption and browser safeguards, and there's no evidence of malware or blacklisting. That's exactly what you'd expect from a legitimate SaaS login page.
Because this is a subdomain, the actual Risk Narrative product likely has its own main site with full details about the service. What matters here is that the authentication is handled by Atlassian's identity platform (id.atlassian.com), which is trusted by millions of users. So if you're asked to log in here, you can proceed with confidence. Just make sure you're on the official Atlassian domain and not a lookalike — the URL itself is a strong signal that you're in the right place.
