Cloud security services for AWS, Azure and GCP

Cloud security services are the assessment, implementation, and monitoring work that protects a cloud environment's identities, network, data, and configuration. Under the shared responsibility model, AWS, Azure, and GCP secure the underlying infrastructure. Everything you deploy on it is yours to secure. A provider typically covers IAM hardening, network segmentation, encryption, threat detection, vulnerability management, incident response, and compliance evidence.

A cloud security consultant reads your cloud environment, ranks what is exposed, and designs the controls that close those gaps. That means reviewing IAM policies, network paths, encryption, logging, and public exposure against a benchmark such as CIS. The output is a prioritized remediation plan. Most cloud security consulting engagements also cover implementation, shipping the fixes as infrastructure code. Control mapping for SOC 2 and ISO 27001 is usually part of the scope.

Pricing depends on account and workload count, and on whether you need an assessment only or ongoing operations. A fixed-scope cloud security assessment of a small AWS estate takes one to three weeks. Remediation is scoped from the findings. Managed security operations are priced monthly against account count, compliance needs, and response SLA. For comparison, one in-house cloud security engineer costs roughly $150,000 to $250,000 per year fully loaded. Contact us for a quote against your environment.

CSPM is continuous monitoring of cloud configuration to find misconfigurations and policy violations. On AWS the building blocks are Config for configuration state, Security Hub for benchmark findings, and GuardDuty for threat detection. CSPM tells you what is wrong. It does not fix it, redesign your network, or respond to an incident. We deploy CSPM as part of a cloud security engagement and then act on what it reports.

The shared responsibility model splits security between the cloud provider and you. AWS, Azure, and GCP secure the physical data centres, hardware, and managed service internals, which is security of the cloud. You are responsible for security in the cloud: IAM, network configuration, encryption, patching, and how your application handles data. Most cloud breaches trace back to the customer side of that line, usually a misconfiguration or an over-permissive identity.

We start with a benchmark read of every account, then work through identity, network, data, and detection in that order. Identity: least-privilege IAM roles, permission boundaries, IAM Identity Center, MFA enforcement, and Access Analyzer to remove over-permissive policies. Network: private subnets by default, reviewed security groups, Network Firewall or Transit Gateway inspection, and WAF at the edge. Data: KMS encryption with scoped key policies, and secrets held in AWS Secrets Manager. Detection: organization-wide CloudTrail, Config rules, GuardDuty, and Security Hub aggregated into one security account. Every control ships as Terraform.

One to three weeks for most environments. A single AWS account with a handful of workloads is usually a week. A multi-account organization with hybrid networking and several Kubernetes clusters runs closer to three. The output is a ranked finding list with reproduction detail, effort estimates, and a diagram of the current architecture. Remediation is scoped separately, so you can take the report to your own team if you prefer.

Infrastructure configuration review is part of a cloud security assessment. Application-layer penetration testing is a separate engagement. Our cloud security work covers IAM, network, encryption, logging, and workload configuration against benchmarks. Exploiting application logic, authentication flows, and APIs is scoped through our VAPT services. That report is CVSS-scored, with proof-of-concept evidence. Many clients run both, in that order.

Yes. We implement the technical controls, automate the evidence, and support you through the audit itself. Controls map to AWS Config rules and conformance packs. Evidence is produced continuously, not gathered in the week before an audit. Scope covers access control, encryption, logging, change management, and vulnerability management. We are not the auditor. SquareOps is ISO 27001 certified, and the frameworks we hold and support are listed on our certifications page.

Yes. Security findings route into the same 24/7 on-call rotation our SRE team runs for production incidents. A critical GuardDuty finding pages a person instead of filling a mailbox. Coverage includes finding triage, containment runbooks per incident type, forensic review from CloudTrail, and a written post-incident report. P1 security incidents carry a 15-minute response target. Managed cloud security operations run standalone or alongside AWS managed services.

AWS is our deepest practice, and we deliver cloud security on Azure and GCP as well. The control categories are the same across providers: identity, network segmentation, encryption, logging, and posture monitoring. We implement them with Terraform so the pattern stays consistent across clouds. On Azure that means Entra ID, Microsoft Defender for Cloud, and network security group design. On GCP it means IAM conditions, Security Command Center, and VPC Service Controls.

Cloud security protects the running environment. DevSecOps protects the path code takes to reach it. Cloud security covers IAM, network design, encryption, posture monitoring, and incident response on the infrastructure you operate. DevSecOps covers secret detection at commit, SAST and dependency scanning in CI, image and IaC scanning, and deploy-time policy gates. The two meet at deployment, and most teams need both.

Ask what the provider does after the report. Many cloud security providers deliver findings and stop, which leaves the work with your team. Check whether remediation is included and whether controls arrive as code you own. Ask who is on call when a finding becomes an incident, and which certifications the provider holds. Ask for a reference in your industry and compliance regime. Confirm you keep the Terraform, runbooks, and dashboards when the engagement ends.
