Cloud Security Services: Close the Gaps You Own
Affix Center · · 8 min read
Quick answer: Cloud security services protect the data, identities, workloads and settings you run on AWS, Azure, Google Cloud or other providers. A good service covers configuration review, identity and access control, logging and monitoring, vulnerability testing, backup and incident response. Start with an assessment, fix the highest risks first, then add continuous monitoring.
Many companies move to the cloud and assume the provider now handles security. Then a storage bucket is left public, an old admin key is never rotated, or nobody notices a login from an unusual country until the bill or the data leak arrives. The cloud provider secured its data centre. Your settings, users and data were always your job.
This guide explains what cloud security services should include, where most cloud setups are weak, and a clear step-by-step plan to close the gaps without slowing your teams down.
What Cloud Security Services Cover
Cloud security services are a set of checks, controls and ongoing monitoring that keep your cloud accounts safe. They can be delivered as a one-time assessment, a project to fix problems, or a managed service that watches your environment every day.
A complete scope usually includes:
- Cloud security posture review: checking storage, networks, databases and services for risky settings.
- Identity and access management: users, roles, service accounts, keys and multi-factor authentication.
- Network protection: security groups, firewalls, private endpoints and web application firewalls.
- Data protection: encryption at rest and in transit, key management and data classification.
- Logging and monitoring: collecting audit logs and raising alerts on suspicious activity.
- Vulnerability management and testing: patching virtual machines and containers, and periodic VAPT.
- Backup and recovery: protected backups that an attacker cannot delete, and tested restores.
- Incident response: a plan, contacts and playbooks for when something goes wrong.
The Shared Responsibility Gap
Every major cloud provider uses a shared responsibility model. The provider secures the physical data centres, hardware and core platform. The customer secures what they put on top: accounts, configuration, operating systems, applications and data. The exact split changes with the service type.
| Layer | IaaS (virtual machines) | PaaS (managed databases, app platforms) | SaaS (Microsoft 365, CRM) |
|---|---|---|---|
| Physical data centre and hardware | Provider | Provider | Provider |
| Operating system and patching | You | Mostly provider | Provider |
| Network settings and firewalls | You | Shared | Mostly provider |
| Application configuration | You | You | Shared |
| User accounts and access | You | You | You |
| Your data and its backup | You | You | You |
The bottom two rows are always yours. That is where most real incidents begin, which is why cloud security services focus so much on identity, configuration and data.
Common Cloud Security Gaps in Indian Companies
These problems show up again and again in cloud reviews. None of them needs exotic tools to fix.
Public storage and open ports
Storage buckets, database ports and remote desktop left open to the internet for "temporary" testing are a common cause of leaks. Automated scanners on the internet find them quickly.
Too many admins and old keys
Developers, vendors and former staff often keep owner or admin rights long after they need them. Access keys created years ago sit in code repositories and laptops.
No multi-factor authentication on key accounts
The root or global admin account without MFA is the single biggest risk in many tenants. See our guide on multi-factor authentication implementation.
Logs switched off or not reviewed
If audit logs are not enabled and kept, you cannot investigate an incident. In India, the CERT-In directions of April 2022 require organisations to report specified cyber incidents within 6 hours and to maintain logs of their ICT systems for 180 days within India. Our CERT-In 6-hour reporting checklist explains what this means in practice.
Backups in the same account
If backups live in the same account with the same admin rights, ransomware or a malicious insider can delete both production data and backups together.
Unpatched virtual machines and containers
Lift-and-shift migrations often move old servers into the cloud exactly as they were, including missing patches and outdated software. Container images built months ago can carry known vulnerabilities into every new deployment. Patching does not stop just because the server now runs in someone else's data centre.
No owner for cloud security
In many companies, the infrastructure team thinks developers handle security settings, and developers think infrastructure does. When nobody owns cloud security, findings pile up and nobody acts on alerts. Naming one owner, even part-time, is often the most useful first step.
How to Secure Your Cloud: A Step-by-Step Plan
This is the order we recommend. It fixes the most likely causes of a breach first and builds steady monitoring after that.
- Take an inventory: List every cloud account, subscription and project, who owns it and what data and applications run in it, including test and forgotten accounts.
- Lock down admin access: Turn on MFA for every user, protect root and global admin accounts, remove unused admins and give people only the roles they need.
- Remove long-lived keys: Find old access keys and secrets, rotate or delete them, and move applications to managed identities or a secrets vault.
- Run a configuration review: Use the provider's built-in security tools or a posture management tool to find public storage, open ports, unencrypted disks and weak policies, then fix the high-risk findings.
- Enable and keep logs: Switch on audit, sign-in and network logs for all accounts, send them to a central place and keep them for at least the period your regulators require.
- Set up alerts that someone answers: Configure alerts for risky events such as new admin users, logins from unusual locations and disabled logging, and name the person or team who responds.
- Protect backups: Keep backups in a separate account or with immutability turned on, and test a full restore at least once a quarter.
- Test from the outside: Commission a VAPT of internet-facing applications and cloud configuration, then retest after fixes.
- Write the incident plan: Document who to call, how to isolate a compromised account and how to meet reporting timelines, then run a short tabletop exercise.
Choosing the Right Delivery Model
Cloud security services come in three common forms. Many companies start with an assessment and then move to a managed model.
| Model | What you get | Best for | Watch out for |
|---|---|---|---|
| One-time assessment | Review report with prioritised findings | First look at an existing cloud setup | Findings that nobody is assigned to fix |
| Remediation project | Hands-on fixing of settings, access and logging | Teams without cloud security skills in-house | Changes made without testing in production |
| Managed cloud security | Ongoing monitoring, alert handling, monthly reviews | Companies with production workloads and compliance duties | Vague SLAs and reports that only list alerts |
When comparing providers, ask for sample reports, the exact list of checks, response times for critical alerts, and who owns fixing each type of issue. Useful questions to ask any provider:
- Which cloud platforms and services do you cover, and which do you not?
- Do you only report problems, or do you also fix them?
- How fast do you respond to a critical alert at night or on a holiday?
- Will you help us prepare evidence for audits and regulators?
- How do you handle our data and your own access to our accounts?

Cloud Security for Regulated and Government Workloads
Some organisations face extra rules on where data sits and how it is protected. Banks and NBFCs follow RBI directions, listed companies have SEBI cyber security expectations, and government departments often need MeitY empanelled cloud services. Before you design controls, list which rules apply to you and what evidence auditors will ask for. Our article on data localisation requirements in India explains the main points. Treat this as general information and confirm specifics with your compliance adviser.
Keep Security From Slowing Delivery
Security that blocks developers gets bypassed. A few habits keep both sides happy:
- Use templates and infrastructure as code with security settings already built in.
- Scan code and container images in the pipeline instead of at the end.
- Give developers safe sandbox accounts so they do not test in production.
- Review cloud costs and security together, because unused resources are both waste and risk. See our tips on cloud cost optimization.
Frequently Asked Questions
What are cloud security services?
They are services that assess, fix and monitor the security of your cloud accounts, covering configuration, identity and access, data protection, logging, vulnerability testing, backup and incident response.
Is my data safe just because it is on AWS or Azure?
The provider secures its infrastructure, but you are responsible for your accounts, settings, users and data. Most cloud incidents come from customer-side misconfiguration or stolen credentials.
How often should we review cloud security?
Run continuous automated checks, review findings monthly, and do a deeper assessment or VAPT at least once a year and after major changes.
Do small businesses need cloud security services?
Yes, if they store customer data or run business systems in the cloud. A small company can start with MFA, access cleanup, logging and protected backups, which cost little and remove the biggest risks.
What is the difference between cloud security and VAPT?
VAPT is one part of cloud security. It tests for weaknesses at a point in time. Cloud security services also include fixing settings, managing access and monitoring every day.
