OCI Has the Security Tools.
Most Deployments Never Configure Them.
OCI ships with Cloud Guard, Security Zones, Vault, and Bastion Service — capable security tools that most deployments leave at default settings or never enable at all. Enabled is not the same as configured. Configured is not the same as effective. Symhas activates, tunes, and integrates every OCI security capability into a coherent Zero-Trust model. Symhas designs and implements Zero-Trust security on OCI — identity-first access, no standing privilege, automated threat detection with auto-remediation, and customer-managed encryption — producing a compliance-ready security posture for SOC 2, ISO 27001, HIPAA, and FedRAMP from the first day the environment is live.

Core Capabilities.
Production-Grade from Day One.

Every capability designed, deployed, and documented by Symhas OCI-certified architects. Fixed price. Fixed timeline. SLA-backed from go-live.

OCI IAM & Identity SecurityIdentity Domains · Policies · MFA · Federation · Conditional access
OCI Identity and Access Management configured for Zero-Trust — every user and service principal authenticated with MFA, access granted by least-privilege policies, and federated identity from Azure AD or Okta so OCI users do not maintain separate credentials.
OCI Identity Domain configuration — MFA enforced, session policies, and password complexity
IAM policy audit — existing policies reviewed for over-permission, corrected and documented
Federation — Azure AD or Okta as identity provider, OCI as service provider
Service principal management — instance principals and resource principals replacing static credentials
Privileged user controls — separate privileged accounts, just-in-time elevation via Bastion
Every OCI access decision verified against identity — no shared accounts, no static credentials, no exceptions
OCI Cloud Guard — Threat Detection & Auto-RemediationDetector rules · Responder recipes · SIEM · Threat Intelligence · Dashboard
OCI Cloud Guard continuously monitors every OCI resource against 200+ security detector rules — identifying misconfigurations, anomalous activity, and threat indicators, with responder recipes that automatically remediate the most common findings without human intervention.
All Cloud Guard detector rules enabled — configuration and activity detectors
Responder recipe configuration — auto-remediation for public bucket, public IP, and weak password findings
Custom detector rules — organisation-specific security policies enforced via Cloud Guard
SIEM integration — Cloud Guard events forwarded to Microsoft Sentinel or Splunk
Threat Intelligence service — known bad IP and domain feeds integrated into detector rules
Security misconfigurations detected and remediated automatically — not discovered in the next quarterly audit
OCI Vault & EncryptionHSM-backed keys · Customer-managed · Key rotation · Secret management
OCI Vault provides HSM-backed customer-managed encryption keys for all data at rest across compute, database, storage, and object storage — so encryption key custody remains with the customer, not Oracle, and key rotation is automated.
HSM-backed master encryption key creation per environment and data classification
Customer-managed key for Oracle Database TDE, Block Volume, Object Storage, and File Storage
Key rotation policy — annual automated rotation with no service disruption
Secret management — API keys, database passwords, and certificates stored in Vault, not in code
Key usage audit — every data decryption event logged and available for compliance review
Encryption key custody with the customer — Oracle cannot access encrypted data without the customer key
OCI Bastion Service & Privileged AccessJust-in-time · Session recording · No standing SSH · PAM · Audit trail
OCI Bastion Service eliminates standing privileged access to OCI compute and databases — engineers request just-in-time sessions that are time-limited, logged, and automatically terminated, with no SSH keys or RDP credentials persisting after the session ends.
Bastion Session types — Managed SSH, Port Forwarding, and Dynamic Port Forwarding
Time-limited sessions — maximum session duration enforced, no indefinite access
Session recording — all Bastion sessions logged with command-level audit trail
Approval workflow — privileged access requests require approval before session is created
No standing SSH keys — compute instances configured with no authorised SSH keys outside Bastion
Zero standing privileged access to production — every session time-limited, every command logged
Delivery Model
Assessment to Production.
Four Phases. Fixed Price.

Go/no-go gates at every phase. Scope and price agreed before week one. No surprises at handover.

01
Security Assessment & Gap Analysis Week 1

Current OCI security posture assessed against CIS OCI Benchmark and target compliance framework. Cloud Guard findings reviewed. IAM policy over-permission analysis. Security Zone gaps identified. Remediation plan produced.

02
IAM Hardening & Identity Security Week 2

IAM policies reviewed and corrected. MFA enforced across all users. Identity federation to Azure AD or Okta configured. Service principals replace static credentials. Bastion Service deployed and standing SSH keys removed.

03
Cloud Guard, Vault & Security Zones Week 3

Cloud Guard all detectors enabled and responder recipes configured. Vault master keys created and data encryption keys rotated. Security Zones applied to production compartments. SIEM integration tested. Auto-remediation validated.

04
Compliance Validation & Handover Week 4

CIS OCI Benchmark score validated. Compliance evidence package produced for target framework. Security team trained on Cloud Guard dashboard and alert triage. Runbooks for access requests documented. Symhas moves to advisory.

Zero Security Findings at SOC 2 Audit. Cloud Guard Live in 4 Weeks.

A global asset management firm migrating Oracle Fusion Finance to OCI had an existing OCI environment with Cloud Guard disabled, no Security Zones, shared service account credentials used for application-to-database connections, and no Vault or customer-managed encryption keys.

Symhas implemented OCI Zero-Trust security in 4 weeks — IAM federated to Azure AD, all shared credentials replaced with instance principals and Vault secrets, Security Zones applied to all production compartments, Cloud Guard activated with 200+ detector rules, and Bastion Service replacing all standing SSH access. SOC 2 Type II audit passed with zero security findings.

Why Symhas
OCI Expertise Built from Production Deployments.
Security Assessment Before Configuration Begins Symhas assesses the current OCI security posture before writing a single policy or enabling a single detector. Every remediation is justified by a specific finding — not a generic hardening checklist applied without understanding the environment.
Cloud Guard Tuned, Not Just Enabled Cloud Guard with default settings produces noise. Cloud Guard with tuned responder recipes and custom rules produces signal. Symhas tunes every Cloud Guard detector against your environment — suppressing false positives and configuring auto-remediation for the findings that matter.
Every Credential Out of Config Files Before Handover Application credentials in config files are one of the most common and preventable OCI security failures. Symhas treats zero hardcoded credentials as a go-live requirement — every connection string, API key, and database password stored in OCI Vault with instance principal authentication replacing static credentials.
Compliance Evidence Generated Automatically Cloud Guard, Vault key usage logs, and Bastion session records are compliance evidence. Symhas configures the evidence collection and export — so the SOC 2 or ISO 27001 auditor receives a structured evidence pack, not a request for screenshots.
No Standing Privileged Access from Go-Live Bastion Service requires removing standing SSH authorised keys from compute instances. Symhas removes all standing SSH keys from production instances before go-live — no exceptions, no legacy access paths left open for convenience.
Security Team Trained on Cloud Guard Operations By handover your security team can triage Cloud Guard alerts, investigate responder actions, and add new detector rules. Symhas certifies the security operations team on OCI Cloud Guard before stepping back — so the first live security event is handled independently.
