For SOC 2, tools are only part of the equation. Auditors are ultimately evaluating whether controls are appropriately designed and actually operate over time, especially for a Type II report. The AICPA’s Security/Common Criteria covers access, risk assessment, monitoring, system operations, change management, and risk mitigation.
If you're starting from scratch, I'd prioritize the stack in this order:
| Priority | Tool/service | What it gives you | Why it matters |
|---|
| 1 | SSO + MFA / IdP | Central identity, MFA, RBAC, onboarding/offboarding | Usually the highest-value foundational control |
| 2 | MDM / endpoint security | Laptop encryption, screen lock, patching, device inventory | Provides evidence that corporate endpoints are controlled |
| 3 | Cloud IAM + logging | Least privilege, admin controls, audit trails | Critical for AWS/Azure/GCP environments |
| 4 | Central logging / SIEM | Security-event collection, alerting, review records | Supports monitoring and incident detection |
| 5 | Vulnerability management | Automated scans, findings, remediation tracking | Demonstrates vulnerabilities are identified and addressed |
| 6 | Git + CI/CD controls | PR reviews, approvals, deployment history | Strong evidence for change management |
| 7 | Backup + recovery | Automated backups and restore testing | Particularly important if Availability is in scope |
| 8 | Incident-response tooling | Alert routing, tickets, runbooks, tabletop evidence | Shows that detection actually leads to response |
| 9 | GRC/compliance platform | Control mapping, evidence collection, policy tracking | Makes the audit substantially easier, but doesn't replace the underlying controls |
| 10 | Vendor-risk management | Vendor inventory, assessments, SOC reports | Supports third-party risk controls |
1. Start with identity and access
I'd make SSO + enforced MFA the first major investment. Use an identity provider such as Okta, Microsoft Entra ID, or Google Workspace and connect it to your cloud, Git provider, production tooling, HR systems, etc.
You want to be able to demonstrate:
- Every employee has an identifiable account.
- MFA is enforced, not merely available.
- Privileged access is restricted.
- Access is granted through an approval process.
- Departing employees are promptly deprovisioned.
- Access is periodically reviewed.
This is particularly valuable because a single identity system can produce evidence for several controls. Current SOC 2 evidence guidance emphasizes provisioning/deprovisioning, MFA, RBAC and access reviews.
2. Lock down employee endpoints
Implement an MDM/endpoint-management platform for company laptops.
At minimum, enforce:
- Full-disk encryption
- Screen lock
- Supported OS versions
- Security updates/patching
- Device inventory
- Remote lock/wipe where appropriate
- Endpoint security/EDR
The auditor doesn't necessarily care which MDM you bought. They care that you can produce evidence showing the policy is enforced across in-scope devices.
3. Secure the cloud and privileged infrastructure
For AWS/Azure/GCP, establish:
- Individual accounts rather than shared credentials
- MFA for administrative access
- Least-privilege IAM
- Separate production/non-production access
- Protected root/break-glass accounts
- Cloud audit logging
- Encryption and managed key management
- Network/security-group controls
Importantly, don't just configure these and forget them. Establish periodic access reviews and retain evidence of the reviews.
4. Centralize logging and monitoring
You need a defensible answer to:
"How would you know if someone performed a suspicious action?"
Centralize relevant logs from:
- Identity provider
- Cloud infrastructure
- Production systems
- Administrative actions
- Git/CI/CD
- Security tools
Then establish alerting and a documented review process. Auditors increasingly want evidence of the process—for example, an alert, investigation/ticket, escalation, and resolution—not merely a screenshot showing that logging is enabled.
You don't necessarily need an enormous enterprise SIEM. A well-configured cloud-native logging/monitoring stack can be sufficient depending on your environment and scope.
5. Implement vulnerability management
Have automated vulnerability scanning for:
- Internet-facing infrastructure
- Servers/containers
- Dependencies
- Endpoints
- Cloud configuration, where appropriate
More importantly, create a remediation workflow with severity-based SLAs.
The evidence chain should look like:
scan → finding → assigned owner → remediation → verification
A vulnerability scanner that produces thousands of findings but never demonstrates remediation isn't particularly useful for an audit.
6. Make your development process auditable
For engineering teams, your Git/CI system can provide excellent SOC 2 evidence.
Require:
- Pull requests
- Peer review
- Appropriate approval before production
- Protected production branches
- CI testing
- Deployment records
- Controlled emergency changes
This directly supports change-management controls.
7. Don't forget backups
If Availability is included in your SOC 2 scope, implement:
- Automated production backups
- Appropriate retention
- Encryption
- Monitoring for failed backups
- Documented RPO/RTO
- Actual restore tests
The last point is frequently overlooked. A successful backup job doesn't prove that you can recover. Evidence of a restore test is considerably stronger.
8. Formalize incident response
Have an incident-response platform/process with:
- Severity definitions
- Escalation paths
- On-call ownership
- Incident tickets
- Communication procedures
- Post-incident reviews
- Periodic tabletop exercises
Even if you've had zero security incidents, you can generate evidence by conducting a tabletop or simulated incident and documenting the response.
9. Add a GRC/compliance platform after the basics
Platforms such as Vanta, Drata, Secureframe, or Sprinto can automate evidence collection and control monitoring. They can connect to your identity provider, cloud, Git, HR, endpoint, and other systems.
But I would not make the GRC platform your first security purchase.
Think of it this way:
Security tools create the controls. GRC software collects and organizes the evidence.
Buying a compliance platform before implementing MFA, endpoint management, access reviews, logging, vulnerability management, etc. mostly gives you a nicer dashboard showing that those things aren't implemented.
The lean startup stack
For a small SaaS company preparing for its first SOC 2, I'd aim for something roughly like:
Identity
→ SSO + mandatory MFA + RBAC
Endpoints
→ MDM + disk encryption + EDR
Cloud
→ IAM + encryption + audit logging + secure configuration
Engineering
→ Git PR approvals + CI/CD + change tracking
Security operations
→ Central logging + alerting + vulnerability scanning
Resilience
→ Automated backups + restore tests
Process
→ Incident response + access reviews + vendor management + security policies
Evidence
→ GRC/compliance platform
That combination covers a large portion of what auditors are likely to examine under the Security/Common Criteria.
One important distinction: Type I vs. Type II
If you're pursuing SOC 2 Type II, start these controls well before the audit. Type II evaluates operating effectiveness over an observation period, so you can't simply install the tools the week before fieldwork and expect a strong evidence history.
The biggest mistake I see in SOC 2 preparation is treating it as "buy security software." The better approach is:
Define control → implement technology → assign owner → operate it consistently → collect evidence → test it internally.
If you tell me your company size (e.g. 10, 50, or 200 employees), cloud provider, and whether you're pursuing Type I or Type II, I can turn this into a prioritized SOC 2 security-tool stack with specific products, approximate costs, and what each one satisfies.
