Pro Tip: Most modern browsers update automatically, so keeping your browser up to date is usually all that's required to ensure compatibility with KaiNexus.
If KaiNexus displays a message that your browser is unsupported or out of date, contact your organization's IT team for assistance updating or replacing your browser.
Allow cookies and JavaScript
KaiNexus requires both cookies and JavaScript to function properly. These features are enabled by default in all supported browsers.
If your organization manages browser settings centrally, contact your IT team to confirm that cookies and JavaScript are permitted for KaiNexus.
Check your device and internet connection
KaiNexus can be accessed from any modern computer, tablet, or mobile device with a reliable internet connection.
There are no special hardware requirements. If your device can comfortably run a supported web browser, it should be able to run KaiNexus.
Network and firewall configuration
If your organization restricts internet access through a firewall or proxy, share this section with your IT team.
Domain allowlisting (recommended)
KaiNexus requires outbound HTTPS (TCP 443) access to the following domains:
| Purpose | Allow |
| KaiNexus Application |
*.kainexus.com |
| Help Center | support.kainexus.com |
| Embedded Training Videos | *.vimeo.com, *.vimeocdn.com |
Recommendation: Allowlist by domain name rather than specific IP addresses. This ensures your configuration continues to work as our cloud infrastructure scales.
IP-based allowlisting
If your firewall requires IP-based rules instead of domain allowlisting, configure access over TCP ports 80 and 443 for the following IP addresses:
| Environment | IP addresses |
| Production | 104.155.134.186, 34.120.99.131, 34.160.106.81 |
| Sandbox and Showroom | 104.196.158.42 |
Email deliverability
KaiNexus sends email notifications for task assignments, mentions, approvals, and digests. To ensure these messages are delivered successfully and not filtered as spam, your email or security team may need to allowlist KaiNexus as a trusted sender.
| Email Type | Sending Address / Domain |
| Support Emails | support@kainexus.com |
| System and Activation Emails | prod.kainexus.com kainexus3.kainexus.com do-not-reply@prod.kainexus.com |
Single sign-on (SSO)
KaiNexus supports SSO using SAML 2.0 and works with identity providers such as Microsoft Entra ID (Azure AD), Okta, and Ping. Refer to the Single Sign-On (SSO) for more information.
