"Proactive Updates and Responsive Support That Stay Ahead of Threats"

5/5

What do you like best about Guardian?

Guardian stands out because of their proactive update schedule and responsive customer support team. They are clearly committed to staying ahead of emerging threats, and whenever we've had a technical question, their support staff has been knowledgeable and quick to assist. Review collected by and hosted on G2.com.

What do you dislike about Guardian?

Due to test connection failure of OnGuard system the jobs get stuck sometimes creating a discrepancy that we need to fix later. Review collected by and hosted on G2.com.

What problems is Guardian solving and how is that benefiting you?

Guardian solves our configuration drift and compliance monitoring challenges. It automates what used to be a tedious manual audit process, allowing us to catch misconfigurations before they become security risks. This benefits me by saving hours of manual reporting time and giving the leadership team confidence in our security posture. Review collected by and hosted on G2.com.

Thank you for the thoughtful review. We really appreciate your highlighting both the strengths and areas for improvement.

It’s great to hear that our proactive updates and responsive support team are making a positive impact. Staying ahead of emerging threats and continuously improving the platform is a core priority for us, and we’re glad that’s coming through in your experience.

We also appreciate your feedback regarding the OnGuard connection issues. Intermittent job failures and downstream discrepancies can be frustrating, and we’re actively working to strengthen integration resilience and error handling across physical access control systems (PACS) to minimize these scenarios and improve recovery workflows.

It’s especially encouraging to hear how Guardian is helping address configuration drift and compliance monitoring. Automating audits and identifying misconfigurations early is a key part of our physical identity and access management (PIAM) approach, saving time, reducing risk, and giving leadership greater confidence in security posture.

Thanks again for your partnership and for sharing such valuable insights. We’re committed to continuing to improve your experience with Guardian.

"Intuitive, Configurable GUI—But Setup and Documentation Rely on Developers"

3.5/5

What do you like best about Guardian?

What is most helpful about Guardian?

The most helpful aspects of Guardian are its simple and intuitive GUI and easy navigation, which make it approachable for users with varying levels of technical expertise. The platform is also highly configurable, allowing it to be adapted to different use cases and organizational needs. Once configured correctly, Guardian provides a streamlined experience that supports efficient system interactions.

What are the upsides of using Guardian?

Guardian offers several key upsides:

User-friendly interface: The clean and straightforward design improves usability and reduces the learning curve for new users.

Ease of navigation: Logical layout and clear workflows make it easy to move through the system and perform required tasks.

Flexibility and configurability: Guardian can be tailored to meet specific business or operational requirements, which is valuable in complex or evolving environments.

That said, one notable drawback is the dependency on Guardian developers for system configuration, which can limit agility and self-service capabilities for internal teams. Additionally, the lack of out-of-the-box documentation and user guides makes it more challenging to onboard users or independently troubleshoot without external support. Review collected by and hosted on G2.com.

What do you dislike about Guardian?

One of the primary dislikes is the strong dependency on Guardian developers for configuration and changes, which limits internal teams’ ability to independently manage or adapt the system. This reliance can slow down updates and reduce overall agility.

Another concern is the lack of out-of-the-box functionality and application guides. The absence of clear documentation and ready-made usage guidance makes onboarding more difficult and increases the learning curve for both new and existing users.

Additionally, the non-standard design of menus can be confusing at times. Menu structures do not always align with common UI conventions, which can impact usability and require extra time for users to locate features or understand workflows. Review collected by and hosted on G2.com.

What problems is Guardian solving and how is that benefiting you?

Guardian is solving the challenge of addressing specialized and evolving requirements that are not always supported by off‑the‑shelf products. One of the most significant benefits has been the developer flexibility and willingness to explore new requirements, even when those needs fall outside standard feature sets. The Guardian team has been highly accommodating and collaborative, working closely with us to understand regulatory and operational constraints.

A major example of this value is the inclusion of capabilities not available in other products, specifically Job Role change audits to support NERC compliance. This functionality directly addresses audit and regulatory needs that would otherwise require manual processes or supplemental tools. By providing this feature within Guardian, the platform helps reduce compliance risk, improves audit readiness, and saves time for internal teams.

Overall, Guardian benefits us by offering a solution that is adaptable, responsive to compliance-driven requirements, and supported by a development team willing to partner on custom needs, rather than forcing our processes to fit rigid, predefined product limitations. Review collected by and hosted on G2.com.

Thank you for such a detailed and thoughtful review. We truly appreciate the time you took to share both the strengths and areas for improvement.

We’re glad to hear that Guardian’s intuitive interface, navigation, and configurability are delivering value. Designing a flexible physical identity and access management (PIAM) platform that can adapt to complex and evolving requirements, rather than forcing organizations into rigid workflows, is a core part of our approach. It’s especially meaningful to see Guardian supporting specialized needs like job role change audits for NERC compliance, helping improve audit readiness and reduce manual effort.

We also sincerely appreciate your candid feedback around configuration dependency, documentation, and menu structure. These are important areas we’ve been actively investing in. Over recent releases, we’ve expanded no-code and low-code configuration capabilities, enhanced self-service tools, and continued to improve in-platform guidance and documentation to better support independent administration and faster onboarding. Simplifying the user experience and aligning navigation more closely with common UI patterns is also an ongoing focus for our product team.

It’s great to hear that our team’s collaboration and willingness to support unique requirements has made a difference. That partnership mindset is something we’re committed to maintaining as we continue to evolve the platform.

Thank you again for your honest feedback and continued partnership. We’re focused on building on this foundation to deliver an even more intuitive, self-service, and scalable experience with Guardian.

"Guardian and Operational Interoperabilty"

5/5

What do you like best about Guardian?

We struggled with multiple legacy platforms. We had a clear vision for a multi-use approach to identity management, and the Alert Enterprise team listened—then Guardian delivered. Guardian addressed interoperability for us by bringing various systems together to drive process improvement, strengthen cost controls, and support governance. There was no need to rip and replace our legacy systems; instead, we gained a single pane of glass that lets us run multiple operations from one dashboard. Truly game changing. Review collected by and hosted on G2.com.

What do you dislike about Guardian?

There’s nothing to dislike about Guardian. In our organization, we too often got distracted by scope creep while developing new strategies. It’s critical not to get pulled off course by every new idea; instead, we need to stay focused on the task and scope, and keep the fundamentals in mind. Review collected by and hosted on G2.com.

What problems is Guardian solving and how is that benefiting you?

Guardian helped us accomplish a significant strategic goal we call "time-to-pay;" the connectivity between contractor time on site, and SAP integration for accurate invoicing. That was a significant challenge we faced and Guardian helped us resolve delivering real dollars back to our operations SG&A. Review collected by and hosted on G2.com.

Thank you for sharing this thoughtful and generous review. We truly appreciate your partnership and confidence in Alert Enterprise Guardian.

We’re especially glad to hear how Guardian supported your vision for physical identity and access management (PIAM) by unifying multiple physical access control systems (PACS) without the need to rip and replace existing investments. Helping organizations consolidate and unify PACS into a single, interoperable platform, while maintaining strong governance and cost control, is a core value of Guardian. Delivering a true single pane of glass for managing operations, employee and contractor access, and identity-driven workflows is exactly what we aim to achieve.

It’s also great to hear how this approach enabled meaningful process improvements while keeping your teams focused on fundamentals. As organizations expand the use of mobile credentials and modern access strategies, staying aligned with clear scope and objectives is essential. Guardian is designed to support scalable PIAM programs that evolve, while keeping access governance, operational clarity, and security at the center.

Thank you again for the trust and collaboration. We’re proud to support your journey toward PACS consolidation and unified identity-driven access, and we look forward to continuing to innovate together.

"Seamless IT–HR to PACS Integration with Guardian"

5/5

What do you like best about Guardian?

Cyber-Physical Convergence: Guardian's most significant strength is connecting IT and HR systems (like Workday or SAP) directly to physical access control systems (PACS) such as Lenel or C-Cure Review collected by and hosted on G2.com.

What do you dislike about Guardian?

Setup Complexity and Integration Hurdles: Some users report that the initial setup of Guardian can be complex and challenging, often requiring a significant amount of time for adjustments. Integration issues, particularly after software updates, have been noted to cause system failures or delays in resolution Review collected by and hosted on G2.com.

What problems is Guardian solving and how is that benefiting you?

Manual Access Provisioning: Eliminates the slow, error-prone process of manually entering employee data into various Physical Access Control Systems (PACS).

Access "Orphanage": Solves the security risk of terminated employees retaining physical access because their badges weren't manually deactivated in time.

Compliance Gaps: Addresses the difficulty of producing real-time audit logs for regulations like NERC CIP, SOC 2, and HIPAA across multiple global sites.

Alert Fatigue: Reduces the noise of thousands of meaningless security events by using the Guardian SOC Insights dashboard to highlight only high-risk anomalies. Review collected by and hosted on G2.com.

"Fantastic End-to-End Access Control Automation with Audit Logs and Provisioning"

5/5

What do you like best about Guardian?

End-to-end automation of an access control request, audit log, and provisioning of access in the access control system. Review collected by and hosted on G2.com.

What do you dislike about Guardian?

The previous version was easier for internal teams to configure updated workflows. Review collected by and hosted on G2.com.

What problems is Guardian solving and how is that benefiting you?

Elimination of manual provisioning/deprovisioning and the reduction of human errors. Guardian also serves as our recertification platform to sensitive areas. Global Security is able to run a recertification of access with very little effort. If area owners do not act upon the recertification within 30 days, the access to the area is revoked automatically without human intervention. The Guardian platform enabled us to deploy over 40 badge printers in strategic offices with high populations which provides much quicker turnaround time between a person making a badge request and the person receiving a fully functional badge. We have not implemented NFC mobile credentials, but we like that the Guardian platform is fully capable of pushing an NFC credential into Apple and Google Wallets. We like the seamless integration of the visitor management platform being integrated with the turnstiles of our facility from a customer service standpoint and logging of the event from a security standpoint. Review collected by and hosted on G2.com.

Response from Willem Ryan of Guardian

Thank you for sharing such a comprehensive and insightful review. We truly appreciate the level of detail.

We’re glad to hear that Guardian is delivering strong end-to-end access control automation, from request and approval workflows to audit logging and provisioning within your physical access control systems (PACS). Eliminating manual provisioning and deprovisioning to reduce human error is a core objective of our physical identity and access management (PIAM) platform, and it’s great to see that impact reflected in your operations.

Your use of Guardian for access recertification, especially for sensitive areas, is a great example of policy-driven governance in action. Enabling Global Security teams to run large-scale recertifications with minimal effort, automated enforcement, and built-in accountability is exactly how Guardian is designed to support compliance and risk reduction. We’re also pleased to hear how Guardian has helped accelerate badge issuance through distributed badge printer deployment, improving both turnaround time and user experience.

It’s exciting to hear that you’re leveraging Guardian’s visitor management integration with turnstiles for both customer experience and security visibility, and that you see value in the platform’s readiness for NFC mobile credentials in Apple Wallet and Google Wallet when the time is right.

Thank you again for your partnership and trust in Guardian. We look forward to continuing to support your access automation, PACS unification, and identity governance initiatives as your needs evolve.
