SIEM has historically been a large enterprise technology — expensive, complex, and requiring a full-time security team to operate. ManageEngine Log360 changes this calculus significantly for Indian SMBs.
But that does not mean every business needs a SIEM. This guide helps you decide whether Log360 is the right investment for your organisation, when to prioritise it, and what a realistic SMB SIEM deployment looks like in India.
What SIEM Actually Does for a Small Business
Before deciding whether you need it, understand what SIEM does:
What SIEM gives you:
- A centralised record of everything that happened across your IT environment
- Automated detection of known attack patterns
- Anomaly alerts when users or systems behave unusually
- Compliance reports that prove your monitoring capability to auditors
What SIEM does NOT give you:
- A firewall or perimeter defence (SIEM sees logs — it does not block traffic)
- Endpoint protection (that is antivirus and EDR)
- Email security (that is a separate product)
- Automatic remediation (SIEM alerts you; humans or SOAR tools act)
SIEM is a visibility and detection layer — it works best when you have other security products generating logs worth monitoring.
Do You Need SIEM? A Decision Framework
Yes — strong case for SIEM if:
You have regulatory compliance requirements: If your business is in BFSI (regulated by RBI), listed on NSE/BSE (SEBI LODR), processes payment cards (PCI DSS), or handles health data (HIPAA), you likely have explicit or implicit SIEM requirements. Log360 is the most cost-effective path to compliance documentation.
You have active directory with privileged users: If you have a Windows domain with more than 10 users and at least one or two admin accounts, AD auditing alone (part of Log360) is valuable. Knowing immediately when a new Domain Admin is created or a service account is modified is worth the investment.
You have experienced a security incident in the past 2 years: A past incident demonstrates real risk. If you suffered a ransomware attack, a data breach, or a credential compromise, SIEM gives you the detection capability to catch the next one earlier.
You have remote employees and VPN: Remote access creates visibility gaps — users connecting from home, from hotels, from mobile devices. SIEM correlates VPN logs with AD authentication to flag impossible travel, credential sharing and access outside normal patterns.
Your business has customer data you are contractually obligated to protect: IT outsourcing companies, BPOs, CA firms, law firms and healthcare providers often have explicit data protection obligations in client contracts. SIEM is the evidence that you are monitoring access to that data.
Probably not yet — if:
You have fewer than 20 employees and no compliance requirements: At this scale, a good firewall (SonicWall TZ, Sophos XGS), endpoint protection, and email security give you a better security ROI than SIEM. Build those layers first.
You have no one who will look at the alerts: SIEM generates alerts. If no one in your organisation will investigate them — or if you have no budget to engage Cloudfy for managed SOC support — the tool sits unused. An unmaintained SIEM is worse than no SIEM (it creates false confidence).
Your IT infrastructure is entirely cloud-based with no on-premise systems: If your entire environment is SaaS (Google Workspace, Microsoft 365, Salesforce) with no on-premise servers, Active Directory or network devices, Log360's primary value props (AD auditing, on-premise log correlation) apply less. Microsoft Sentinel or Google Cloud Security Command Centre may be more appropriate cloud-native alternatives.
When Does an Indian SMB Actually Need SIEM?
Based on common deployment scenarios, the typical trigger for an Indian business to deploy Log360 is one or more of:
| Trigger | Business Type |
|---|---|
| RBI audit requirement | NBFC, bank, payment aggregator, microfinance institution |
| SEBI LODR 2024 compliance | Listed company, promoter entity |
| Client contract requirement (ISO 27001 or SOC 2) | IT services company, BPO, SaaS vendor |
| PCI DSS assessment failure | Payment processor, merchant with direct card processing |
| Post-incident response | Any business that experienced ransomware or data breach |
| Growing IT team (10+ servers) | Manufacturing, healthcare, education, logistics |
| Cyber insurance requirement | Any business applying for or renewing cyber liability policy |
Log360 for Common Indian SMB Scenarios
Scenario 1: NBFC with 150 Employees (RBI-regulated)
A mid-sized NBFC in Pune processes loan applications, disburses loans and collects EMIs. The RBI Cyber Security Framework applies — the NBFC's IT team (2 people) needs to demonstrate security monitoring to their internal auditor and RBI.
What Log360 provides:
- AD auditing module tracks all staff access to loan management system
- Firewall log integration shows network-level threats
- RBI Cyber Security Framework compliance report auto-generated monthly
- Alert if any staff account accesses loan data outside 9am–6pm window
- Incident documentation for RBI circular compliance
Deployment model: On-premise (data residency requirement), managed by Cloudfy.
Scenario 2: IT Services Company, 80 Employees (ISO 27001 certification required by enterprise client)
A software development firm in Bengaluru is bidding on a contract with a large banking client. The client's security team requires ISO 27001 certification within 6 months, which requires demonstrating security monitoring capability.
What Log360 provides:
- ISO 27001 compliance report covering Annex A 8.15 and 8.16 controls
- Evidence of access control monitoring (AD audit logs)
- Security incident records (if any) with investigation documentation
- Developer access to production environments monitored (a common client requirement)
Deployment model: Cloud SaaS (fastest deployment; ISO 27001 certification timeline is tight).
Scenario 3: Listed Manufacturing Company, 400 Employees (SEBI LODR 2024)
An auto components manufacturer listed on NSE needs to comply with SEBI LODR Regulation 62A. Their Company Secretary asks the IT team what cybersecurity monitoring is in place.
What Log360 provides:
- SEBI compliance report generated monthly for CS review and board reporting
- Real-time incident detection with 6-hour reporting capability
- Incident register (required by SEBI for listed companies)
- Annual audit report for cybersecurity committee
Deployment model: On-premise or hybrid; quarterly compliance reports scheduled.
Scenario 4: CA Firm, 35 Employees (Post-Incident)
A CA firm in Delhi suffered a ransomware attack — a staff member opened a malicious email attachment and the attacker encrypted 3 workstations and a file server before being contained. The firm's cyber insurance claim was paid, but the insurer now requires evidence of security monitoring as a condition for renewal.
What Log360 provides:
- Ransomware staging detection (bulk file access, network share access patterns)
- USB device monitoring (common lateral movement vector)
- Alert on new software installation on endpoints
- Log360 Free edition covers 5 devices initially; upgrade as budget permits
Deployment model: Cloud SaaS (easiest for small team); Cloudfy managed alert review.
The Minimum Viable SIEM for an Indian SMB
If you are an Indian SMB with limited IT resources and budget, here is the minimum Log360 configuration that provides genuine value:
Log Sources (Priority Order)
- Domain Controllers — Active Directory is your most valuable source. Every login, every admin action.
- Primary firewall — Perimeter threat visibility.
- File server — Access to sensitive business files (client data, financial records).
- Cloud platforms — Microsoft 365 or Google Workspace admin logs (account changes, admin activity).
Four to six log sources, well-configured, deliver more value than 50 poorly-monitored sources.
Alert Rules (Start Simple)
- New Domain Admin account created
- 10 failed logins in 5 minutes from same IP
- User login outside business hours (configure your actual hours)
- Admin account login from new device
- Firewall blocks spike (5x normal rate in one hour)
Five well-tuned alert rules, reviewed daily by a human, are more effective than 500 rules that flood an inbox and get ignored.
Compliance Report Schedule
Generate your applicable compliance report (RBI/SEBI/ISO 27001/PCI DSS) monthly. Review it before you archive it. This discipline builds the evidence trail that auditors look for.
Total Cost for an Indian SMB — Realistic Budget
For an Indian business with 50 log sources (reasonable for a 50–100 person company):
| Component | Annual Cost (Estimated) |
|---|---|
| Log360 Standard (50 sources, subscription) | ₹60,000 – ₹1,00,000 |
| Log360 UEBA add-on (optional) | ₹20,000 – ₹40,000 |
| Server hardware (on-premise only) | ₹1,50,000 – ₹3,00,000 (one-time CapEx) |
| Cloudfy deployment + config (one-time) | ₹50,000 – ₹1,50,000 |
| Cloudfy managed SOC support (optional) | ₹60,000 – ₹1,20,000/year |
Year 1 total (on-premise, with Cloudfy deployment): ₹3,20,000 – ₹5,60,000 for a genuinely operational SIEM.
For a cloud SaaS deployment (no hardware cost), Year 1 can be as low as ₹1,50,000–₹3,00,000.
This is accessible for most Indian SMBs where a compliance requirement or a past incident justifies the investment.

Frequently Asked Questions
Can a 2-person IT team manage Log360?
Yes, with the right setup. The key is starting with a small number of well-tuned alert rules and using Log360's pre-built compliance reports rather than building custom ones. Cloudfy also offers managed SOC support where our team reviews alerts on your behalf — freeing your internal team from daily SIEM operations.
What is the difference between SIEM and a firewall?
A firewall sits at your network perimeter and decides which traffic to allow or block. SIEM collects logs from your firewall (and everything else) and analyses them to detect attacks that are already happening — including lateral movement after an attacker has already passed the firewall. They are complementary, not alternatives.
Is Log360 better than a managed SOC service?
Log360 is a tool; a managed SOC is a service. Many Indian SMBs use both: Log360 as the underlying SIEM platform, with Cloudfy providing the managed alert review and incident response as a service layered on top. This gives you full log data ownership (you are not sending raw logs to a third party) while outsourcing the operational burden.
How quickly can Log360 be operational for an Indian business?
Cloud SaaS deployment with core log sources can be operational within 24–48 hours. On-premise deployment typically takes 3–5 business days including server provisioning. Full production deployment with all integrations, alert tuning and compliance report configuration takes 2–3 weeks.
