I'm wondering how realistic it is to rely on automated asset discovery versus just maintaining a solid inventory of our security assets. It seems to me that if we have good change management and proper asset tracking in place, we shouldn't need to rely on these discovery tools at all—everything should be documented as we deploy it. However, these tools seem to exist to fill the gaps left by poor processes, especially when it comes to shadow IT in the cloud, where unauthorized resources can be spun up with ease.

Using continuous discovery helps minimize the exposure window for those unknown assets, even though it doesn’t completely prevent them. Network scans cover on-prem items, while API polling can catch cloud resources. It’s not ideal since it’s still reactive rather than proactive. Ideally, enforcing infrastructure-as-code would ensure everything goes through approved pipelines, but convincing developers to stick to that can be tricky.
Absolutely, the cloud sprawl issue is a big deal. People can spin up test environments that morph into production without anyone realizing it. By the time discovery tools catch onto them, they've potentially been running unsafely for months, which is really concerning.
Every workplace I've been at has had some form of shadow IT. Even high-level managers can buy devices independently without involving IT. It’s clear that both asset tracking and discovery tools are necessary.
Automated asset discovery is definitely needed, even if your inventory is solid. There's always a chance that someone could deploy unauthorized assets without you knowing. A thorough inventory doesn't solve that visibility issue.
This all comes down to the importance of auditing. It's unrealistic to assume humans will never make mistakes or that everything will always go according to plan. Regular checks are essential.
If you haven't been managing assets from the beginning, then it’s a challenge, for sure. You simply cannot protect what you aren't aware of. Plus, asset management systems track more than just where assets are; they provide crucial info like patch levels and system performance metrics.
In a perfect world, just having a good inventory should be enough, but many clients still lean on automation for asset management. It gives some leeway if a mistake happens—like if one device falls behind on patches, the discovery tool flags it. Plus, it identifies unauthorized assets and can trigger alerts to lessen admin workload. Overall, I think these tools make managing assets much easier and reduce risk significantly. The choice really depends on how much value a business places on this.
If you run discovery tools and find nothing out of place, then your setup is likely more organized than mine!
