GCP Cloud Security Services
Google Cloud Platform powers modern applications and data workloads, but GCP security requires specialized expertise. Misconfigured IAM policies, exposed resources, and complex organizational structures create risk. We help organizations secure their GCP environments with expert-led assessment, continuous monitoring, and remediation guidance.

GCP Security Challenges
GCP offers powerful security capabilities, but its unique model creates challenges:
IAM and Resource Hierarchy Complexity
GCP's resource hierarchy (Organization, Folders, Projects) provides granular control but creates complexity:
- IAM policies inherited across the hierarchy can create unexpected permissions
- Service accounts with excessive roles across multiple projects
- Primitive roles (Owner, Editor, Viewer) granting more access than intended
- Cross-project access patterns that are difficult to audit
- Workload Identity configurations with overly broad permissions
Service-Specific Misconfigurations
Each GCP service has unique security considerations:
- Cloud Storage - Publicly accessible buckets, missing encryption, overly broad ACLs
- Compute Engine - Firewall rules allowing unrestricted access, unpatched instances
- Cloud SQL - Public IP enabled, weak authentication, missing encryption
- Cloud Functions/Cloud Run - Overprivileged service accounts, exposed endpoints
- GKE - Kubernetes misconfigurations, insecure workload deployments
Multi-Project Sprawl
GCP environments accumulate projects across teams and applications. Without proper organization through Folders and Organization Policies, security posture becomes inconsistent and visibility is fragmented.
Data Analytics Security
GCP's strength in data analytics (BigQuery, Dataflow, Vertex AI) creates unique security challenges around data access, sharing, and governance that many organizations struggle to address.
Shared Responsibility
Google secures the underlying infrastructure, but you're responsible for securing your workloads, data, and identity configurations. GCP's different approach requires specific expertise.
Our GCP Security Services
Managed CSPM for GCP
We run enterprise cloud security platforms like Orca Security and Wiz on your behalf, providing:
- Continuous scanning of your GCP projects for misconfigurations
- Expert triage and prioritization of findings (not just raw alerts)
- Actionable remediation guidance for your team
- Compliance mapping to SOC 2, HIPAA, PCI DSS, and other frameworks
GCP Security Assessment
A comprehensive evaluation of your GCP security posture:
- IAM policy and service account analysis
- Network architecture review (VPCs, firewall rules, Cloud Armor)
- Data protection assessment (encryption, access controls)
- Logging and monitoring configuration review
- Compliance gap analysis for your target frameworks
Ongoing GCP Security Support
Fractional security leadership focused on your GCP environment:
- Security architecture guidance for new GCP deployments
- Incident response support for GCP-specific issues
- Security questionnaire assistance for GCP-related questions
- GCP security best practices training for your team
GCP Security Best Practices
IAM Best Practices
- Use predefined roles instead of primitive roles (Owner, Editor, Viewer)
- Follow least privilege for all users and service accounts
- Use Workload Identity for GKE instead of service account keys
- Implement Organization Policies for guardrails across projects
- Regularly audit IAM bindings using Policy Analyzer
Data Protection
- Enable encryption at rest for all data stores (Cloud Storage, BigQuery, Cloud SQL)
- Use Cloud KMS for key management with proper rotation
- Enable encryption in transit for all services
- Configure Cloud Storage bucket policies to prevent public access
- Use VPC Service Controls for data exfiltration prevention
Network Security
- Design VPCs with proper segmentation and private subnets
- Use firewall rules with service accounts for identity-based access
- Implement Cloud Armor for public-facing applications
- Enable VPC Flow Logs for network visibility
- Use Private Google Access and Private Service Connect
Monitoring and Detection
- Enable Cloud Audit Logs for all projects
- Configure Security Command Center for security findings
- Use Cloud Logging with proper retention and analysis
- Implement alerting for critical security events
- Consider Chronicle for SIEM capabilities
Compliance on GCP
SOC 2 on GCP
Google provides SOC 2 reports for GCP infrastructure, but you need to demonstrate controls for your workloads:
- IAM policies and access management procedures
- Encryption configuration and key management
- Logging and monitoring implementation
- Change management processes
- Incident response procedures
HIPAA on GCP
For healthcare workloads:
- Use GCP services covered under Google's BAA
- Implement proper PHI encryption and access controls
- Configure Cloud Audit Logs for audit requirements
- Ensure proper network segmentation for healthcare data
- Document your shared responsibility for HIPAA controls
PCI DSS on GCP
For payment card data:
- Use PCI-compliant GCP services and configurations
- Implement network segmentation using VPCs and firewall rules
- Enable proper logging and monitoring for PCI scope
- Maintain documented evidence of controls
- Regular vulnerability scanning and remediation
FedRAMP and Government Workloads
For government contractors:
- Use Google Cloud for government for FedRAMP requirements
- Implement required security controls per NIST 800-53
- Maintain documentation and evidence for authorization
- Continuous monitoring with Security Command Center
Getting Started with GCP Security
Start with Assessment
Most organizations begin with a GCP security assessment. We connect to your GCP organization, evaluate your current posture, and provide prioritized recommendations. This gives you a clear picture of risks and a roadmap for improvement.
Continuous Monitoring
After initial assessment, ongoing monitoring ensures new resources are deployed securely and existing configurations don't drift. Our managed CSPM service handles this continuously.
Expert Support
Whether you need help implementing recommendations, preparing for compliance audits, or responding to security incidents, we provide the GCP security expertise you need without hiring a full-time specialist.
Need Help Securing Your GCP Environment?
Our managed CSPM service provides continuous GCP security monitoring with expert triage and prioritized remediation guidance.
Frequently Asked Questions
What GCP security services should we be using?
At minimum, enable Cloud Audit Logs for audit logging, Security Command Center for security findings and posture management, and Cloud Logging for centralized logging. For most organizations, we also recommend Cloud Armor for web applications, Cloud KMS for key management, and VPC Service Controls for data protection. The specific mix depends on your workloads and compliance requirements.
How do you assess GCP security without access to our organization?
We use service accounts with read-only IAM roles to assess your GCP environment. This provides visibility into configurations without the ability to make changes. The service account follows Google Cloud best practices for third-party access and can be removed at any time. Our CSPM platforms use similar read-only access for continuous monitoring.
What's the difference between Security Command Center and third-party CSPM?
Security Command Center provides native GCP security posture management and threat detection. Third-party CSPM platforms like Orca and Wiz offer multi-cloud visibility (if you also use AWS or Azure), often deeper analysis, better prioritization algorithms, and more comprehensive compliance mapping. For GCP-only environments, Security Command Center Premium is a good foundation, but many enterprises benefit from additional tooling.
How long does a GCP security assessment take?
Initial assessment typically takes 2-3 weeks depending on the size and complexity of your GCP environment. This includes project discovery, automated scanning, manual review of critical configurations (especially IAM and data access), and report generation with prioritized recommendations. Larger organizations with many projects or complex data analytics workloads may require additional time.
Do you help with GCP security architecture for new projects?
Yes, we provide security architecture guidance for new GCP deployments. This includes VPC design, IAM strategy with proper role structure, data protection approach, logging and monitoring setup, and compliance considerations. Getting security right from the start is more efficient than remediating issues later.
