How Companies Can Improve Visibility in Multi-Cloud Security Environments
Three months ago, a company experienced a data breach. It took them four days to determine where the issue had occurred, as they had services running simultaneously in AWS, Azure, and Google Cloud. By the time they tracked down the compromised server, the hackers had already grabbed what they wanted and disappeared.
The problem wasn’t that their security was terrible. The problem was that they couldn’t see their entire cloud solutions architecture from one place. Each cloud provider has its own dashboard, logging system, and approach to doing things. Trying to monitor all three simultaneously is like watching three different security camera feeds on three separate screens in three other rooms.
Planning and Improving Visibility
Most companies didn’t plan to end up with multiple cloud providers. It just happened over time. The marketing team signed up for AWS three years ago for a web project. The engineering department began using Google Cloud because it required specific machine learning tools. Then the company acquired another business that was already running everything on Azure, and nobody wanted to spend six months migrating it all.
Suddenly, you’ve got critical business data scattered across three different cloud platforms and no single place to monitor all of it. Each platform gives you security alerts in entirely different formats. AWS sends you one type of notification, Azure sends another, and Google Cloud sends something altogether different.
I watched one security team attempt to manage this with spreadsheets. They’d manually check each cloud dashboard every morning, copy information into Excel, and try to spot patterns. It took them three hours daily to get a basic picture of what had happened overnight. They still missed things because humans looking at spreadsheets cannot catch everything. That approach doesn’t scale, and it certainly doesn’t work when dealing with actual security threats that move quickly.
Why Infrastructure Matters
The first thing that helped was centralising all the security logs into one system. Instead of logging into AWS, then Azure, then Google Cloud separately, everything flows into a single dashboard you can actually monitor.
We implemented this for a retail client last year. Set up their cloud solutions architecture so that all security events from every platform are fed into a single central logging system. Now, when something suspicious occurs anywhere in their infrastructure, it appears in the same place with the same format.
Their security team went from spending half their day just gathering information to actually responding to threats. Response time for incidents dropped from hours to minutes because they could identify problems immediately, rather than searching for them across three different systems. The key is picking a logging platform that speaks all three cloud languages fluently. You need something that can pull data from AWS, Azure, and Google Cloud without losing essential details in translation. We used Splunk for that client, but there are other options depending on your budget and needs.
Automated Alerts That Make Sense
Once everything’s in one place, you can finally set up alerts that work across your entire cloud solutions architecture instead of just one piece of it.
You have customer data stored in AWS, but your analytics run in Google Cloud and your backups reside in Azure. Under the old fragmented system, you’d never notice if someone accessed customer data in AWS, then immediately ran unusual queries in Google Cloud, then started copying large amounts of data to Azure.
With centralised visibility, you can create alerts that watch for these cross-platform patterns. The system sees the whole picture and flags behaviour that only makes sense when you’re looking at everything together.
We set this up for a healthcare company managing patient records. Started catching security issues they’d been missing for months because the suspicious activity was spread across multiple clouds. One incident involved someone accessing records in AWS, processing them in Azure, then trying to export them through Google Cloud. Each step looked legitimate, but the sequence was clearly wrong. The automated alert caught it within minutes. Under their old system, they probably never connected those dots.
Bridging The Visibility Gap
The most enormous visibility gap I see is companies losing track of user permissions across different clouds. Someone obtains AWS access for a project, moves to a different team, receives Azure access there, leaves the company, and yet still has active credentials in Google Cloud from two years ago.
This creates massive security holes that are invisible because the permission lists exist in three separate locations. The fix is using a single identity management system that controls access across all your cloud platforms. When someone leaves or transitions to a new role, you update it once, and their access is revoked everywhere simultaneously, eliminating orphaned accounts that could be compromised.
I helped migrate a financial services company to this model last quarter. Every single one was a potential entry point for hackers, and nobody even knew they existed because they were scattered across different cloud solutions’ architecture components.
Making The Multi-Cloud Security Work
Centralize your logs. Pick one platform that can ingest security data from all your clouds.
Standardize your alerts. Build monitoring rules that watch across platforms instead of within them. Look for patterns that only show up when you see the complete picture.
Unify access control. Utilize single identity management that governs all your cloud platforms from a single location. Makes it way easier to track who can access what.
Automate everything possible. Humans can’t watch three dashboards simultaneously. Let automated systems do the monitoring and alert you when something’s actually wrong.
The visibility problem in multi-cloud security isn’t going away. More companies are ending up with this setup every month, whether they planned for it or not. However, you can’t secure what you can’t see, and you definitely can’t see it if you’re trying to watch everything from three different angles simultaneously.
