I need an experienced network-security specialist to guide us through ISO 27001 compliance. Our infrastructure is already segmented behind NG firewalls, but we have not yet aligned every control, document set, and monitoring practice with the standard. The engagement centres on analysing our current network posture, identifying the exact gaps against ISO 27001 Annex A controls, and then implementing or fine-tuning the technical safeguards that will satisfy the external auditor. What I expect you to handle • Gap analysis of existing network architecture and security policies against ISO 27001 requirements • Practical remediation plan with priorities, owners, and realistic timelines • Configuration hardening or rule-set adjustments (switching, routing, firewall, VPN, IDS/IPS) carried out remotely in coordination with our IT team • Creation or update of required artefacts: risk register entries, Statement of Applicability, network-specific SOPs, and evidence logs • Pre-audit walkthrough to make certain every mandatory control can be demonstrated Acceptance criteria Your work is considered complete when an independent ISO 27001 auditor confirms closure of all network-security non-conformities and accepts the evidence pack you prepare. Strong familiarity with ISO 27001 clauses, Annex A controls, and hands-on experience in network hardening are essential. Tools you are comfortable with—whether they are Nmap, Nessus, Wireshark, or enterprise SIEM platforms—are welcome, so long as they align with best practice and do not interrupt business operations. The project will be executed fully remote; most tasks can be scheduled during EU business hours, but I can accommodate occasional off-hours maintenance windows for live configuration changes.

Having spent a considerable amount of my career in cybersecurity, Risk management, and compliance consulting. I bring to the table profound, hands-on experience that will ensure a seamless execution of your ISO 27001 network-security compliance. From conducting Penetration testing with sophisticated tools like Nessus and Acunetix to running intrusive tests with Kali Linux, it's this practical experience in combination with my CEH and CISSP certifications that makes me the perfect fit for your project. I approach consulting just as you do when looking for an expert: less of a simple handshake after delivering a report, but more so concentrating on actually fixing what I find. As such, expect me to provide you with actionable recommendations underpinned by realistic timelines and priorities—a roadmap to remediation that ensures future compliance. An important factor we both appreciate is minimization of any interruptions in your business operations. Exercising discretion is my utmost priority and is essential as we schedule tasks during EU business hours but also accommodate occasional off-hours maintenance windows for live configuration changes.

Hi, I've done this exact type of engagement before — NG firewalls in place, controls partially aligned, auditor deadline looming. I know where the gaps usually hide and what it takes to close them cleanly. On your SoA and Risk Register question: tell me what you have and I'll work from there. If they're half-built, I'll finish them. If they don't exist yet, I'll build them properly against your actual setup. I'll handle everything you listed — gap analysis, hardening, documentation, evidence pack, pre-audit walkthrough — and I won't call it done until your auditor does. Worth a quick call?

Hi, I can support you in aligning your current infrastructure with ISO 27001 by focusing on gap identification and compliance readiness. From your description, it seems your network setup is already structured with segmentation and NG firewalls, which is a strong starting point. The next step is ensuring these controls are properly mapped, documented, and aligned with ISO 27001 requirements. I have hands-on experience working in an RBI-regulated NBFC environment where I worked on: • GRC gap analysis and control mapping • Information security policies aligned with ISO 27001 • Risk assessment and compliance preparation • Practical implementation of security controls For your requirement, I can: • Map your existing controls against ISO 27001 clauses • Identify gaps in network security and documentation • Provide a structured compliance roadmap • Suggest practical improvements aligned with real operations My approach focuses on how controls actually work in your environment, not just documentation. Happy to understand your current setup in more detail and support your compliance journey. Thanks, Swati
