Cloud security challenges commonly include misconfigurations, human errors, and weak identity and access management. These challenges can all lead to vulnerabilities that may result in data theft and loss.
Your data moved to the cloud to help your business scale—but the attackers moved right along with it.
The traditional office perimeter has slowly vanished, making cloud security challenges an increasing concern for businesses. For a growing organization, the shift to a cloud security solution provides incredible flexibility, but it also creates a complex web of identities and settings that are notoriously difficult to manage. If you aren't actively watching these configurations, you're essentially leaving your digital front door unlocked in a neighborhood that never sleeps.
Below are the top cloud challenges facing organizations in 2026 and what you need to know to stay ahead of them.
1. Misconfigurations
In the cloud, your security is defined by your settings rather than a physical perimeter. A misconfiguration is essentially a digital “whoopsies”—like leaving an Amazon S3 bucket set to public or forgetting to restrict a database. Since cloud tools are built for easy sharing, they often default to being open, leaving the heavy lifting of security to your team.
It can only take one wrong click to turn a private folder into a public link. Threat actors don’t need to break in when this happens; they just walk through the unlocked door. For growing businesses, keeping track of every toggle in Microsoft 365 or Google Workspace is a lot to ask, but these tiny oversights are often what lead to the biggest leaks.
2. Human error
Cloud settings can be confusing, and even the most seasoned teams make mistakes. The sheer volume of settings and features inside platforms like Microsoft 365 can trip up anyone. When you’re moving fast to support a growing business, it’s easy to overlook a single checkbox that governs how data is shared or who can access a specific app.
A classic slip-up is leaving a storage bucket public, thinking it’s only accessible to your team when it’s actually open to the entire internet. Sensitive files get exposed simply because a user tried to make a task easier and accidentally bypassed a security rule. These small, human moments are exactly what threat actors look for to get a foot in the door.
3. Weak identity and access management
Often, people have way more access than they actually need. It’s tempting to give everyone “Global Admin” status to avoid IT tickets, but that’s like giving every employee a master key to the entire building. If an attacker steals just one of those sets of keys, they have free rein to creep around your most sensitive data.
Stolen credentials are still the top way attackers get into your cloud. When identity rules are loose, a single compromised password lets an adversary move sideways through your network. They don’t have to work hard to find your crown jewels if your setup already gives them a straight path. Keeping access tight means that even if one account is hit, the rest of your business stays safe.
4. Data breaches and loss
A cloud data breach not only makes headlines but is also a massive headache for any company. Whether it’s sensitive customer info or internal IP, once data leaves your cloud, you can’t get it back. Often, this isn't about a complex heist—it's just someone syncing a local folder to a personal cloud or a guest user having permissions they should've lost months ago.
The fallout is both lost files and the hit to your reputation while you scramble to notify everyone involved. For a growing business, the cost of cleaning up after a breach can be a heavy lift. It’s why keeping a close eye on where your data lives and who is touching it is so important for staying resilient.
5. Insecure APIs
Think of APIs (application programming interfaces) as the doors that let your different cloud apps talk to each other. They’re great for getting work done fast, but if those doors aren't locked, anyone can walk right in. If an API is left open or poorly protected, it creates a direct path for someone to pull data from your cloud without ever needing a set of credentials.
Attackers specifically target APIs with weak authentication to stay under the radar while stealing sensitive information. It’s a common gap for scaling businesses that rely heavily on third-party integrations. Without a watchful eye, these connections can become the weakest link in your security posture, letting outsiders bypass your usual defenses.
6. Visibility gaps
You can’t protect what you can’t see. When you use multiple providers—like Microsoft 365 for email but n Google Workspace for managing files—you often end up with blind spots. Each platform has its own logs and alerts, and jumping between them makes it easy to miss the trail of an attacker moving from one to the other.
These gaps are a major win for threat actors. If your small IT team is stuck looking at three different dashboards, they might not see a suspicious login in one place that matches a weird file download in another. Creating a single, unified view of your endpoints and identities is the only way to make sure no one is hiding in the corners of your cloud.
7. Shadow IT
Shadow IT happens when people use apps or cloud tools that your IT team doesn't know about. Usually, it's just a teammate trying to be more productive—maybe they find a free PDF converter or a project management tool that’s easier to use. But because these tools aren't vetted, they often lack the security controls your business needs to stay safe.
This creates massive blind spots where your cybersecurity isn't being managed at all. If an employee puts sensitive company data into an unapproved app, you have no way to see who else is looking at it or if that app's security is up to snuff. It’s a quiet risk that turns your organized cloud into a wild west of unmanaged data.
8. Skilled staff shortage
The cloud moves fast, and finding people who know how to secure it is a struggle. There’s a massive gap between the number of open security roles and the number of people with the right skills to fill them. For a growing business, trying to hire a dedicated cloud security expert can feel impossible when you're competing with the giant tech firms for the same talent.
This shortage means small IT teams often have to be “jacks of all trades” (and masters of none). When you’re busy fixing printers and managing servers, it’s hard to find the time to become an expert in the latest Microsoft 365 security patches. This is where many businesses get stuck—they have the tools, but not enough hands on deck to keep watch 24/7.
9. Supply chain and third-party risks
Your security is only as strong as your weakest link. That’s the saying, right? In today’s cloud-first world, your business likely relies on dozens of outside software providers and vendors to get work done. If one of those partners has a weak link, that vulnerability can travel straight through the connection and into your own environment.
A breach at a software provider can quickly become a breach for you. Attackers target tools used by thousands of companies to gain a backdoor into all of them at once. For lean operations, it means you have to vet your vendors carefully. When you trust a third-party app with your data, you’re trusting their security team as much as your own.
10. Compliance and regulations
Keeping up with rules like GDPR, CMMC, or HIPAA is a full-time job. Each region and industry has its own set of requirements for how you handle data, and the cloud adds a layer of complexity because your data might be sitting on a server halfway across the world. One mistake in how you store customer information can lead to heavy fines and unwanted attention.
The challenge is that compliance isn't a one-and-done task. As you grow and use more cloud services, staying non-compliant becomes a real risk. It’s hard for a small IT team to keep track of every changing law while also keeping the lights on. You need a way to see if your cloud settings actually meet the standards you're held to, or you're just crossing your fingers and hoping for the best.
11. Account hijacking
Account hijacking is exactly what it sounds like: an attacker takes over a legitimate user’s cloud account to act on their behalf. This is a favorite move for threat actors because once they’re in, they don't look like an intruder—they look like your coworker. They can send emails, change settings, or download files without raising red flags.
We often see this start with a simple phishing link or a reused password. Once the attacker gets in, they often set up email forwarding rules to steal sensitive info or divert payments. For scaling businesses, this is why Managed ISPM is so important—it helps you spot the shady behavior that signals an account is no longer under your control.
12. Insider threats
Not every threat comes from a shadowy figure outside your business. An insider threat is someone with legitimate access—like an employee or a contractor—who uses it to cause harm. While we often think of disgruntled people looking for a payday, many insider threats are actually accidental. A person might share a folder with the wrong permissions or move data to a personal device just to work from home more easily.
Whether it’s a mistake or a deliberate choice, the result is the same: your data is exposed. These are some of the hardest risks to catch because the person is supposed to be there. This is where having a clear view of identity behavior helps. By looking for patterns that don't fit—like someone downloading a massive amount of data at 3am—you can catch a problem before it walks out the door.
13. Denial-of-service attacks (DDoS)
A distributed denial-of-service (DDoS) attack is like a digital traffic jam. Attackers flood your cloud services with so much fake traffic that your real customers and employees can’t get through. While major cloud providers have some built-in protection, a targeted hit can still slow your apps to a crawl or make your website go dark right when you need it most.
For a scaling business, even an hour of downtime is a big deal. If your team can’t access their files or your customers can't log in, work stops, and revenue takes a hit. These attacks are often used as a distraction. While your IT team is busy getting the lights back on, the attacker might be trying to slip through a back door unnoticed.
14. Shared infrastructure vulnerabilities
The cloud is built on shared space. Even though your data is private, you’re technically sharing the same physical hardware with other companies. While cloud giants like Microsoft and Google do a great job of keeping everyone separated, a vulnerability in the underlying software (the hypervisor) could potentially let a noisy neighbor or an attacker peek into your environment.
These types of flaws are rare, but they’re high-stakes. If a threat actor finds a way to break the isolation between users, they could gain access to data without ever touching your specific network. While you can delegate the hardware externally, you still need to keep a watchful eye on your own security posture to stay resilient.
15. Poor or lack of encryption
Encryption acts like a digital paper shredder, with only you having the tape to put the pieces back together. If your data isn't encrypted while it's sitting in the cloud (at rest) or moving across the web (in transit), anyone who intercepts it can read it. Some businesses assume their cloud provider handles this automatically, but settings are often left in plain text by default or use weak keys that are easy to crack.
A lack of encryption makes a thief's job easy. If an attacker gets into an unencrypted storage bucket, they walk away with everything. For a growing business, this is a massive risk to customer privacy and intellectual property. Ensuring your data is unreadable to anyone without the proper key is a basic step that keeps a minor slip-up from turning into a total data disaster.
16. AI-powered attacks
In 2026, AI has gone from a cloud security news buzzword to a primary tool for attackers. They’re now using AI to automate the majority of an attack, from scouting your cloud setup for weaknesses to writing custom malware on the fly. This shift to machine-led attacks means threats move faster than any human team can keep up with, making real-time monitoring a necessity rather than a luxury.
We’re also seeing a massive rise in trust exploitation through deepfakes. Attackers can now use AI to clone a CEO’s voice or create a synthetic video for a quick request to bypass security rules. Because these AI-driven tactics look and sound exactly like your teammates, they can trick even the most cautious people into handing over cloud credentials or authorizing fraudulent payments.
17. Cloud-targeted ransomware
Ransomware has moved far beyond just locking up your local servers. Attackers are now going straight for the source—your cloud environment. Instead of just encrypting files on a single laptop, they target the underlying cloud infrastructure to lock out your entire business from platforms like Microsoft 365 or Google Workspace. It’s a faster, more effective way for them to demand a payday because it brings all your work to a dead stop.
A newer tactic we’re seeing is extortion without encryption. Attackers slip into your cloud, steal sensitive data, and threaten to leak it unless you pay up. Because they aren't actually locking your files, they can stay hidden for much longer, bypassing traditional antivirus tools. For a scaling business, this means your defense has to focus on identity and configuration—if they can't get in, they can't hold your data hostage.
18. MFA fatigue
Multi-factor authentication (MFA) is a must, but it has a human limit. MFA fatigue occurs when an attacker who already has a user’s password repeatedly sends login approval requests to the user’s phone. The goal is to wear the person down until they click “Approve” just to make the annoying notifications stop.
It’s important to note that this fatigue often sets in long before an attacker even shows up. People are so tired of constant prompts throughout their workday that they become less cautious, treating a security alert like a pesky pop-up rather than a warning. For a growing business, this is a reminder that while MFA is a great first step, you also need to look at the context of the login, like why someone is trying to access your cloud from a different country in the middle of the night.
19. Data egress fees
While not a direct threat, data egress fees are sneaky cloud security challenges that can wreck a small IT budget. These are the costs cloud providers charge you to move your data out of their network. Many growing businesses find themselves locked into a provider because the cost of moving their data to a more secure or affordable platform is simply too high. It’s a financial hurdle that can stop you from making the best security choices for your team.
This becomes a security issue when an attacker triggers a massive data transfer. If someone compromises your cloud and starts exfiltrating your data, you’re not just losing your files—you’re also being billed for the privilege of the attacker stealing them. These surprise costs can hit a lean operation hard, turning a security breach into a double-whammy financial crisis.
What is cloud security?
Cloud security is the set of tools, rules, and technologies that protect your digital information when it’s hosted on someone else's servers. It’s the process of ensuring that only the right people can see your files in Microsoft 365 or Google Workspace, and that those files stay private even as they move across the internet.
Think of it as a shared responsibility. While providers like Microsoft or Google help keep the building secure, you’re responsible for locking the doors and windows of your specific rooms. Cloud security helps you manage those locks, ensuring your configurations are correct, your user identities are verified, and your business stays resilient against the modern tricks threat actors use to get inside.
Why does cloud security matter?
The cloud is where your business lives. It’s where you store your best ideas, your customers’ trust, and the day-to-day work that keeps the lights on. If your cloud isn't secure, your entire operation is on shaky ground. Cloud security is about stopping threats and ensuring your team can work without looking over their shoulders.
For a growing business, a single slip-up in the cloud can be a massive setback. Staying secure matters because:
-
Trust is everything: Customers expect you to keep their data safe. Losing that trust is much harder to fix than a technical glitch.
-
Uptime is productivity: A breach can lock you out of your own tools, bringing work to a screeching halt.
-
Resilience is a superpower: Knowing your settings are right lets you focus on growing your business instead of worrying about the what-ifs.
Cloud security is about peace of mind. It’s the baseline that lets a lean operation compete with the big players. When you know your endpoints are healthy and your identities are locked down, you’re free to do what you do best.
Cloud security best practices
Securing the cloud doesn't have to be a guessing game. While the technical side can get deep, the best approach for a lean operation is to focus on the fundamentals first. Staying resilient is less about having every possible tool and more about making sure the tools you do have are set up right.
Cloud security best practices should start by locking down who can get into your systems. This means using strong, context-aware MFA and ensuring people have only the access they need to do their jobs—no more, no less. From there, it's about keeping a constant eye on your settings to catch anything before it becomes a problem.
Cloud security solutions, made simple
The cloud is a powerful tool for any growing business, but it shouldn't come with a side of constant worry. Between configuration drift, identity risks, and growing concerns around AI threats, keeping a lean operation safe is a tall order. But you don’t have to be a Fortune 500 company to have enterprise-grade protection.

FAQ
What is the top risk in cloud security?
Misconfiguration remains the number one risk because it’s so easy to get wrong. A single misplaced click or an overlooked setting can turn a private database into a public link, giving threat actors an open door.
What are the top three cloud computing attacks to be aware of?
Identity-based attacks like phishing and account hijacking are the most common ways for adversaries to get a foot in the door. You also need to watch for Adversary-in-the-Middle (AiTM) attacks that bypass MFA and AI-powered deepfake scams that trick people into giving up access.
What security disadvantages are inherent to the cloud?
The main downside is the shared responsibility model, which can be confusing for small IT teams to manage. Because your data lives on someone else's hardware, you lose physical control and gain a wider attack surface that requires constant monitoring of settings and identities.
