Cisco Catalyst Center vs. Nmap

Would recommend Cisco Catalyst Center to medium to large scale organizations that have many cookie-cutter sites and the resources to properly provision all their devices. I would not recommend to teams that do not have a strong network engineering team that can navigate the various intricacies of the platform.

If you're a sysadmin, or anyone who's had to deploy network services, you've almost certainly had to use Nmap at some point or other. Need to see what devices are on your LAN? Nmap can tell you that. Want to check which ports your web server has open to the internet? Nmap is your friend.

Nmap is a powerful command-line tool and has many options that require some reading of documentation to get the best out of (although generally straightforward). If the thought of working at the command-line scares you (presumably not if you're reading this review), then you may want a much simpler tool, or at least check out Zenmap GUI.

• Again, the ease of use of the APIs and the API Explorer provides the tools needed to write these custom workflows that allow us to do a lot of the automation we’re doing now, saving hundreds of hours by using those tools.
• The product is very intuitive, and there is a lot of support out there in the DevNet community to help with that.

• NMap provides a very fast and a very thorough network "sweep" that allows you to quickly map out exactly what's on your network.
• NMap is highly configurable. The "canned" choices are very good in most instances, but using various switches and options, you can create a very specific scan and get exactly the results you're looking for.
• NMap is easy to use. Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away.

• Within its Tasks - Audit, it can sometimes allow plaintext data, including passwords, to be seen. There should be functionality to detect password usage and appropriately obfuscate the data.
• Occasionally, Catalyst Center does not sync changes properly within templates, which requires deleting and reconfiguring the template version. Better processes here would be beneficial.

• The GUI version on Nmap could use some improvement with the options that are available to do scans. For example, they could make it easier to select options for the different types of scanning for people who are beginners
• There are no abilities to schedule a scan in the Nmap tool.
• An intensive scan sometimes takes too much time to complete.

I think new products are often "half-baked" or over hyped when they release, as was the case with DNAC. We were well ahead of the curve in acquiring it. But as it has matured it is now a fantastic addition to our infrastructure. I think we are easing into a stage where it is hard to envision a large organization NOT having Catalyst Center in place. If for nothing outside of the mapping and troubleshooting aspects; using it as a "source of truth".

Cisco DNA Center is going to help us in security, simplicity and ease of administration. Cisco DNA Center is complete management and control platform that simplifies and streamlines network operations. Cisco DNA Center offers a single dashboard for every core function in your network. With this platform, IT can become more nimble and respond to changes and challenges faster and more intelligently.

Nmap uses are very practical and I don't think there is a better tools for what Nmap does. It is open-sources that therefore there is no cost to use it. It offers a number of benefits, including but not limited to network mapping, port scanning and more. It is very reliable as a network scanning tool.

El soporte de CISCO DNA Center es muy bueno, responden a mis dudas pero no he tenido oportunidad de reportar un incidente o determinar un tiempo de respuesta critico. The support of CISCO DNA Center is very good, they answer my questions, but I have not had the opportunity to report an incident or determine a critical response time.

There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.

It was informative, but the labs were not available long enough for us to get intimately familiar with CCNA before it was closed. The course instructor was well informed and got us as close to ready as she could.

Cisco Catalyst Centeris basic zero-touch provisioning out of the box. You just rack and stack the switches, patch 'em in, and the controller pushes the config automatically. No need to console into every single box or spend hours script-running over CLI.The AI-driven assurance and telemetry are top-tier. Instead of getting flooded with useless syslog alerts when a link drops, it correlates the telemetry data to give you proactive health checks. It literally pinpoints wireless anomalies and bandwidth chokepoints before the users even start opening tickets.It handles fabric microsegmentation like a boss through SD-Access and TrustSec. You can easily enforce group-based policies right at the hardware level. It drops IoT gear, guests, and corporate traffic into their own secure buckets dynamically, without you having to manage a trillion messy VLANs and ACLs.

Alternatives to Nmap (other IP scanners) are often much more limited in what they can do; They often only allow you to scan a specific subset of ports or a limited number of IP addresses in one command. Nmap is unrestricted in that regard. What makes Nmap stand out above the rest, is the complete network analysis package you get with it. It allows IP scanner, network deep-dives, hardware analysis, vulnerability analysis, encryption detailing, and so much more, in one free application

• I have used it for upgrading devices, and it's does a great job at that, however out operations team for whatever reason has not adopted the feature.
• Overall it feels like Cisco Catalyst Center has been huge waste of time. I feel like my time would be better spent on other projects and looking at other products and tools

• Nmap with Wireshark is free, so it's been a great combo team to gather info and test.
• It's allowed us to avoid fines from false positives and to fix actual issues ourselves.
• Great for finding hosts, helps keep the network secure.
