Cybersecurity Services in Delhi
NexaSource serves Delhi enterprises from our nearby Noida HQ — a short drive across the Yamuna for on-site work. Delhi is one of India's most regulated commercial environments: government-adjacent corporates, embassy-linked firms, BFSI head offices, large hospital chains, and the Nehru Place IT-trading hub. We bring enterprise-grade controls without the multinational consultancy price tag.

- Quick coverage from Noida: On-site engineers reach Connaught Place, Nehru Place, Saket, Okhla, Bhikaji Cama Place, and Aerocity within four hours of dispatch — faster outside peak traffic. For active incidents we pre-position engineers.
- Government and PSU adjacency: Many Delhi customers operate alongside government, PSU, or regulated entities. We are familiar with CERT-In incident-reporting requirements (six-hour mandate), MeitY guidelines, and audit expectations from CAG-linked auditors.
- Healthcare-sector experience: Delhi has India's densest concentration of large hospital chains and diagnostic networks. Our team has hardened HIS/RIS systems, segmented medical-device networks, and prepared organisations for NABH and DPDP Act-aligned patient-data controls.
- Vendor neutrality matters here: Delhi corporates often inherit a multi-vendor stack from past system-integrator engagements. We rationalise it across Palo Alto, Fortinet, Cisco, Microsoft, and CrowdStrike — not push a single product line.
- Data residency for regulated work: For customers handling Indian citizen data, our managed-service telemetry stays in Indian data centres by default.

Threat patterns we are seeing in Delhi (2025-2026)
A snapshot of patterns our SOC and incident-response team have observed in engagements with Delhi customers over the past 12-18 months.
CERT-In incident-reporting non-compliance
Delhi enterprises remain a top focus for the CERT-In six-hour reporting mandate. We see organisations either over-reporting (every alert) or under-reporting. Mitigation: pre-defined classification matrix, documented escalation, and a tested 24×7 contact tree.
Hospital ransomware
Delhi NCR hospitals have been hit by Akira, Black Basta, and Phobos affiliates over the past 12 months. Mitigation: EDR on every clinical endpoint, immutable backups, segmentation of HIS from medical devices, IR retainer.
Business email compromise on trading houses
Vendor-impersonation invoice fraud targeting Nehru Place trading firms and Okhla manufacturers. Mitigation: DMARC enforcement, MFA on email, finance-team out-of-band verification training.
Embassy and NGO targeting
Spear-phishing and watering-hole attacks against Delhi-based diplomatic missions and human-rights NGOs continue. Mitigation: phishing-resistant MFA, hardened browser policies, mobile EMM, and credential-rotation hygiene.
Frequently Asked Questions
Do you have an office in Delhi?
We do not yet have a city-centre Delhi office. Our team operates from our Noida HQ (Sector-2) and dispatches on-site to Delhi addresses with a typical four-hour window. For ongoing managed customers we hold weekly steering calls at your premises.
What is your on-site SLA inside Delhi?
Standard four-hour dispatch from Noida for active incidents in Central, South, and East Delhi. West and North Delhi typically run four to five hours. For platinum SLAs we pre-position engineers near your premises.
Can you help us comply with the CERT-In six-hour incident-reporting mandate?
Yes. We help Delhi customers build the classification matrix, the on-call tree, the report templates, and the evidence-collection workflow needed to meet the six-hour CERT-In window without flooding the regulator.
Do you serve large hospital chains?
Yes. We have hardened HIS/RIS environments, segmented medical-device networks (DICOM, HL7), deployed EDR across clinical endpoints, and prepared organisations for NABH and DPDP-aligned patient-data audits.
Do you work with PSUs and government-adjacent corporates?
We work with private corporates that have PSU customers or board members from a PSU/regulated background. We do not currently bid on direct GeM tenders, but partner with empanelled SIs where the engagement is appropriate.
Which Delhi business districts do you cover most often?
Connaught Place, Nehru Place, Saket, Bhikaji Cama Place, Aerocity, Vasant Vihar, Okhla Industrial Estate, and Patparganj IT Park.
