Possible disadvantages of UptimeRobot

  • Limited Advanced Features in Free Plan
    Some advanced features, such as shorter monitoring intervals and additional notification options, are only available in the paid plans.
  • Occasional False Positives
    Some users have reported experiencing false positives, where UptimeRobot incorrectly identifies downtime, potentially causing unnecessary concern.
  • SMS Alerts are Paid
    While email notifications are free, SMS alerts require additional cost, which might be a disadvantage for users who rely heavily on SMS for instant notifications.
  • Limited Server Locations
    The number of server locations for checking uptime is somewhat limited compared to competitors, which can affect the accuracy of uptime reporting in different geographies.
  • Custom Notifications Setup Complexity
    Setting up customized notifications can be somewhat cumbersome and not as straightforward, requiring users to navigate through multiple settings.
  • Limited Free Tier
    The free plan has some limitations, such as a maximum of 50 monitors and a 5-minute monitoring interval, which may not be sufficient for larger or mission-critical setups.
  • Advanced Features are Paid
    Most advanced features, including SMS alerts and more frequent monitoring, require a paid subscription, which might be a barrier for some users.
  • Data Retention
    The free tier only retains monitoring data for 3 months, which may be insufficient for long-term analysis and historical comparisons.
  • Integration Complexity
    Integrating UptimeRobot with other services and platforms might require some technical know-how, making it a bit challenging for non-technical users.

Questions & Answers

As answered by people managing UptimeRobot and runZero.

What's the story behind your product?

runZero's answer:

runZero was founded in 2018 by HD Moore, well known in the industry as the creator of Metasploit. Over the last 25 years, HD has led penetration testing teams, helped build three successful security products, and pushed the boundaries of security research.

Throughout HD's storied career, one persistent fact stood out: organizations that care about security are still frequently compromised through assets they don’t know about. Even those who invest in mature security and IT programs still struggle to achieve full visibility into increasingly dynamic environments that endure constant change in assets, networks, and clouds. HD founded runZero to solve this problem and lay the foundation for the next generation of exposure management.

What makes your product unique?

runZero's answer:

The runZero Platform is the only total attack surface and exposure management solution that combines powerful proprietary active scanning, native passive discovery, and API integrations. Unifying these discovery approaches makes our platform unique in its ability to discover and provide accurate, detailed fingerprinting for all IT, OT, and IoT devices across on-prem, cloud, and remote environments.
