WHY AUTOMATION

Why infrastructure automation (IaC), now?

With multi-cloud and containers now the norm, infrastructure has become a living system that changes hundreds of times a day. Manual operations create chronic problems — human error, inconsistency between environments, no audit trail, and deployment delays. Secrets like API keys, database passwords and certificates leaking into Git or chat happen every year, and recovery costs are enormous.

Expernet's infrastructure automation solution manages "Infrastructure as Code" centered on HashiCorp Terraform, Vault and Consul. Terraform declares and version-controls AWS, Azure, GCP and on-premises infrastructure in the same code; Vault centrally issues, rotates and audits secrets automatically; and Consul auto-discovers service-to-service communication and builds a Zero-Trust-based service mesh. Combined with Fortinet FortiSOAR, this extends to playbook-based automated response for security events.

Automation isn't complete just by adopting tools — it's a journey that requires changing an organization's operating culture and permission structure alongside it. Drawing on IaC delivery experience across finance, manufacturing and public-sector customers, Expernet provides a phased transition roadmap from manual operations to automation, pipeline design, and training and technical support.

Core Values
Eliminates alert fatigue
Automatically classifies and deduplicates thousands of daily alerts from SIEM, firewalls and endpoints — only real threats reach the analyst.
Playbook-driven automated response
IP blocking, account deactivation, malware isolation, ticket creation — drag-and-drop playbooks execute automatically within minutes.
Single pane of operations
Unifies FortiGate, FortiSIEM and third-party EDR/SIEM in a single console. Handle every action in one place, without switching tabs.
SYSTEM UPGRADE

From manual operations to full automation

The infrastructure operating paradigm changes. A single line of code controls hundreds of cloud resources.

01
Infrastructure provisioning
terraform apply

Move beyond manual clicks in the cloud console — declare infrastructure as code and deploy automatically. Reproduce the exact same environment, any time.

02
Change approval & history
Git PR Review

Move beyond configuration changes concentrated in one person — the team reviews and approves via Git pull requests, with every change automatically recorded.

03
Environment consistency
Single codebase

Provision dev, staging and production from the same Terraform code, eliminating configuration drift at the source.

04
Secrets & credentials
Vault dynamic issuance

Issue database passwords and API keys only at the moment of use, and revoke them automatically on expiry. Hardcoded-leak risk disappears.

05
Audit & compliance
100% automatic record

Every infrastructure change is captured in Git history — proving exactly when, who and why in code.

06
Cloud spend
Auto-detect & clean up

Automatically detects and cleans up unused instances, snapshots and IPs, cutting off cost leaks you never noticed.

USE CASES

Real-World Deployment Cases

Finance · Security Operations (SOC)

Automated SOC alert response (FortiSOAR)

Problem Problem

Three security staff manually triaged over 3,000 SIEM alerts a day — real threats were caught too late, letting damage spread.

Solution Solution

FortiSOAR playbooks auto-classify and prioritize alerts. Malicious IPs are blocked automatically on FortiGate, and account takeovers trigger automatic AD deactivation.

Result Result

95% faster alert processing, MTTR cut from 8 hours to 15 minutes, SOC team refocused on high-value threats.

IT Services · Multi-Cloud

Unified multi-cloud infrastructure management

Problem Problem

AWS, Azure and on-prem VMware were each managed separately, causing configuration drift and inefficiency.

Solution Solution

Terraform now manages all three environments from a single codebase. Standard modules provision new environments within 2 hours.

Result Result

90% faster deployment, 80% fewer incidents caused by configuration errors.

Fintech · DevOps

Building a secrets management framework

Problem Problem

Teams shared database passwords over email and chat; departed employees' accounts were never cleaned up — a security risk.

Solution Solution

Deployed Vault with least-privilege secrets access per team member and dynamic database credentials, eliminating shared accounts entirely.

Result Result

100% audit trail on secrets access, achieved ISO 27001 certification.

Code-review-based infrastructure change eliminates manual mistakes.
A SIEM (Security Information and Event Management) collects and analyzes logs to generate alerts — it is detection-focused. FortiSOAR is a SOAR tool that receives the alerts a SIEM generates and automatically executes response actions. Used together, FortiSIEM and FortiSOAR automate the entire detect → analyze → respond pipeline.
Yes — in fact it delivers even greater impact in resource-constrained environments. FortiSOAR playbooks automatically handle the volume of alerts that one or two security staff could never process manually, freeing the team to focus on real threats.
No. Terraform's import feature can bring existing infrastructure under code management. It's common to apply IaC to new resources first and migrate existing infrastructure gradually.
HashiCorp was acquired by IBM in 2024, but the product lineup (Terraform, Vault, Consul) continues to be developed and supported. The BSL licensing change to the open-source editions does not affect enterprises using enterprise licensing.
Yes, that's possible. However, Terraform state files (tfstate) can store sensitive data like database passwords in plain text, creating a security risk. For enterprise environments, we recommend using Vault alongside it.
