Remote access security

Okta enables secure access for remote users. In addition to collaboration tools to assist with communication among remote teams, the solution provides cloud and on-premises services through deployment on a SSO solution. Okta’s remote users can further secure their internal network with remote use by adding MFA as a supplementary layer of security. MFA can be used to connect on-premises applications and access servers remotely.

Duo also provides secure remote access for a remote workforce that can be used without a virtual private network. The Duo Network Gateway is Duo’s remote access proxy, which can streamline secure remote access for organizational members. The Duo Network Gateway enables authorized users access to organizations’ web applications, websites, and SSH and RDP servers based on permission controls.

Security analytics and monitoring features

Okta’s security analytics feature enables users to gain visibility of their monitored security data. Their security monitoring widget allows users to view their organization’s metrics and suspicious activity reported by users. These metrics are automatically updated each time the widget loads.

Okta’s HealthInsight feature audits organization security settings and displays ways to improve security, while the ThreatInsight feature provides information about log-in attempts for suspicious activities and allows users to log events for auditing or block suspicious network traffic. (Figure C)

Duo’s Trust Monitor surfaces security events to administrator users. It leverages up to 180 days of historical data to create a baseline of normal user and device behavior through analysis and modeling. It then scores deviations from the baseline behavior. This monitoring feature assesses the risk of the effect of each component and creates threat models to evaluate them. (Figure D)
