    Microsoft
    Microsoft Defender External Attack Surface Management is particularly well-suited for discovering, inventorying, and continuously monitoring the external attack surface, especially in environments with heavy Microsoft adoption. It is less suitable as a standalone solution for internal scanning, real-time attack detection, automated remediation, or advanced application testing. Microsoft Defender External Attack Surface Management es especialmente adecuado para descubrir, inventariar y monitorear continuamente la superficie de ataque externa, sobre todo en entornos con fuerte adopción de Microsoft. Es menos adecuado como solución única para escaneo interno, detección de ataques en tiempo real, remediación automática o pruebas avanzadas de aplicaciones.

    Serena CM is well suited to highly controlled, audited, and process driven environments. It will allow strict segregation of duties, and change traceability. If implemented correctly it will help you quickly build trusts with your auditors. It is also well suited to environments that require constant branching and merging. Due to the complexity of the product and learning curve for your development and operations team it may be overkill in a small shop with loose rules

    • Code Promotion: Dimensions CM allows supervisors to control changes to code, in that they delegate requests to developers, and act as a gatekeeper prior to promoting to the next environment. This functionality is configurable so you can set up a workflow that best fits the structure and requirements of your own company.
    • Code Repository for changes and versioning: Code can be checked out by item or by synchronizing folders. Code revisions can be compared against other revisions or work files. Item histories show which developers made which modifications, and which supervisor and operations personnel were involved in assigning the request and promoting the code to each environment. Additionally a pedigree will show a stream diagram which graphically displays branches and merges.
    • Deployment: Serena Change Management offers help automating deployment including integrations with SVN and Jenkins. Its newer versions also have a powerful graphical deployment automation tool (Serena Deployment Automation- SDA). It comes with a certain amount of licenses built-in. If you have a many nodes to deploy to there will be separate licensing costs for that.

    • The only major negative that I have encountered with Serena CM product is that the very power and flexibility of the tool means there is a risk that you will make a mess of things. In other words it gives you plenty of rope to tangle yourself with. I recommend careful, well thought out deployments implementing the built in roles and workflows that can be turned on and configured, using a consistent methodology.
    • My experience with the Serena help desk support has not been impressive. Though reasonably polite and diligent, the technicians were well trained, and often gave bad advise and terrible scripts. On several occasions I had to rewrite scripts they have me; if I had run them as provided they would have caused even more difficulties than the problem I was trying to solve. I speak of the support in the past tense because I conditioned myself not to call them, it was usually just easier to solve nay problems my self. They do have a good account management team though, and for any major issues you can go thru them.

    Because Microsoft Defender External Attack Surface Management is part of the broader Microsoft Defender family (including Defender XDR, Entra ID, Azure Security, Sentinel, etc.), it:
    Shares identity, endpoint, and threat context across tools
    Reduces the need for custom integrations or connectors
    Works in a “single pane of glass” experience for SOC analysts
    Why it matters:
    Organizations already invested in Microsoft security tools gain greater contextual insight and lower operational overhead.

    Serena CM is superior to Microsoft Team Foundation Server (TFS) in overall functionality, but does not have very good native integration with Microsoft. Therefore in a Microsoft centric shop with no audit needs ,TFS would be better. Otherwise I would choose Serena CM
