When to consider professional support to strengthen your security posture
Cloud computing has revolutionized how SMBs operate. It offers flexibility, scalability, and cost savings that were once out of reach for smaller teams. But while the cloud eliminates the need for physical servers and bulky infrastructure, it doesn’t eliminate responsibility.
Many businesses assume cloud providers handle all security — but that’s a costly misconception. Under the shared responsibility model, providers secure the infrastructure, while customers (that’s you) are responsible for securing data, configurations, and user access.
Let’s look at the top cloud security risks that SMBs face today — and what you can do to stay protected.
Top 8 Security Risks of Cloud Computing
1. Misconfigured Cloud Settings
Even the most secure platform can be compromised by a single incorrect setting. Misconfigurations — like leaving storage buckets public or failing to enforce encryption — remain one of the top causes of cloud data breaches.
How to Avoid It
Enable strong access controls: Restrict permissions to the principle of least privilege.
Turn on encryption: Protect data both at rest and in transit.
Use configuration management tools: Microsoft Defender for Cloud and AWS Config can flag risky settings automatically.
Conduct regular audits: Align reviews with frameworks such as the NIST Cybersecurity Framework or CISA Cloud Security Guidelines.
2. Weak or Reused Passwords
Still using “Welcome123” somewhere? You’re not alone — but you’re also not secure. Weak credentials are one of the simplest ways attackers gain access to cloud environments. Once inside, they can move laterally to extract data or plant ransomware.
How to Avoid It
Implement Multi-Factor Authentication (MFA): A single extra verification step blocks most credential-based attacks, highlighting the need for two-factor authentication.
Adopt a password manager: Encourage staff to use complex, unique passwords.
Monitor for credential leaks: Use tools like Microsoft Entra ID Protection to detect compromised logins.
3. Lack of Visibility and Monitoring
Cloud environments are dynamic — users log in from multiple locations, workloads scale automatically, and new integrations appear overnight. Without consistent monitoring, it’s impossible to spot anomalies or unauthorized behavior early.
How to Avoid It
Centralize visibility: Use a Security Information and Event Management (SIEM) tool such as Microsoft Sentinel.
Set up alerts: Flag suspicious login attempts, data transfers, or configuration changes.
Automate responses: Tools can isolate compromised accounts before attackers cause real damage.
4. Inadequate Data Protection and Backup
Accidental deletion, a ransomware attack, or a provider outage can all lead to data loss. If your only copy of data lives in the cloud, your business continuity is at risk.
How to Avoid It
Follow the 3-2-1 Backup Rule: Three copies of data, on two types of media, with one off-site (or offline).
Use immutable storage: Prevent backups from being altered or deleted.
Test restoration regularly: A backup you can’t restore is just a very expensive decoration.
5. Insider Threats
Not every breach comes from an outside attacker. Disgruntled employees, contractors, or even well-intentioned users can mishandle data, accidentally share credentials, or override security controls. All of these, along with a handful of unusual cybersecurity threats, demand our attention.
How to Avoid It
Enforce role-based access control (RBAC): Limit data access to what’s necessary for each role.
Monitor user activity: Use behavioral analytics to detect unusual patterns.
Educate employees: Security awareness training is one of the most cost-effective defenses.
6. Compliance Gaps
Industries like healthcare, finance, and retail operate under strict data protection laws — from HIPAA to PCI DSS to state-level privacy acts. A single oversight can lead to steep fines and reputational damage.
How to Avoid It
Know your requirements: Identify which regulations apply to your business.
Map cloud controls to frameworks: Align configurations with NIST CSF, ISO 27001, or Microsoft Secure Score benchmarks.
Maintain documentation: Keep evidence of security measures and audits — regulators love paperwork.
The biggest misconception about the cloud? Thinking “Microsoft handles it.” In reality, cloud providers secure the platform, but you’re responsible for securing what’s on it — your users, data, and settings.
How to Avoid It
Review provider responsibility charts: Microsoft, AWS, and Google publish detailed breakdowns.
Secure what you control: Identity, access, and data are always your responsibility.
Create clear internal policies: Define who manages what within your organization.
8. Shadow IT and Unapproved Apps
Employees often connect third-party apps to the cloud without approval — from calendar tools to AI plugins. Each unverified integration is a potential backdoor for data exposure.
How to Avoid It
Inventory all connected apps: Use cloud access security brokers (CASB) or built-in tools like Microsoft Defender for Cloud Apps.
Set approval workflows: Require IT review before new tools are connected.
Educate employees: Explain the risks of connecting personal or unverified apps to company data.
Common Mistakes SMBs Make in Cloud Security
Even with the best intentions, SMBs sometimes skip crucial steps in the name of convenience or cost savings.
Watch Out For:
Assuming “the cloud is automatically secure”
Ignoring small misconfigurations that compound over time
Treating security as an IT-only problem instead of a company-wide responsibility
Taking time to review these mistakes can prevent data breaches and downtime — both of which are far more expensive than prevention.

FAQs
-
Misconfigurations and weak access controls are the most common causes of SMB cloud breaches. Even simple oversights — like open storage buckets — can expose sensitive data.
-
Yes, but under the shared responsibility model, users must secure configurations, permissions, and data. Providers protect infrastructure — you protect your data.
-
At least quarterly, or after any major system change. Regular reviews help identify gaps before attackers do.
-
Absolutely. Managed service providers (MSPs) like Kelley Create offer proactive monitoring, patching, and compliance support that small businesses can’t always maintain in-house.
-
Not compared to a breach. Many best practices — MFA, encryption, backups — are low-cost or built into existing tools. The key is proper setup and monitoring.
