Job DescriptionNetwork Security LeadAccenture | Technology | Infrastructure & Cloud EngineeringRole OverviewAccenture is looking for an exceptional
Network Security Leadto join our Network Infrastructure Engineering practice. This is a senior individual contributor and client leadership role for someone who combines
deep enterprise network security expertisewith the commercial instinct and communication skills to win trust at the highest levels of a client organisation.
You will be the
go-to security authoritywithin the network practice - the person clients call when they need to understand how to modernise their security architecture, navigate a compliance challenge, or respond to an evolving threat landscape. You will own relationships with a portfolio of
blue-chip enterprise clients, guiding them on their journey toward Zero Trust, SASE, and SSE adoption, whilst shaping and delivering the work that follows.
This role demands someone who is equally comfortable
whiteboarding a ZTNA architecture with a room full of CCIEs, presenting a business case to a CISO, and rolling up their sleeves to produce the proposal, design, or deliverable that gets the deal done. Versatility is not optional - it is the role.
Key ResponsibilitiesClient Relationship & Advisory- Own and developtrusted senior relationshipsacross a portfolio of blue-chip enterprise clients, acting as their primary network security advisor within Accenture.
- Advise clients atCISO, CTO, and VP Infrastructure levelon network security strategy, architecture modernisation, and risk posture improvement.
- Leadclient workshops, discovery sessions, and executive briefings, facilitating complex technical and strategic conversations with confidence and clarity.
- Serve as atrusted thought partneras clients navigate regulatory compliance requirements, security frameworks (e.g. NIST, ISO 27001, NIS2, DORA), and evolving threat environments.
- Identify and shapenew opportunitieswithin existing accounts, recognising client challenges and translating them into well-formed propositions.
Technical Leadership- Provideauthoritative guidanceon enterprise network security architecture, with particular depth across:
- SASE(Secure Access Service Edge) - architecture, vendor landscape, migration strategies
- SSE(Security Service Edge) - SWG, CASB, DLP, RBI and integration patterns
- ZTNA / Zero Trust- principles, frameworks, identity-centric access, micro-segmentation
- Next-Generation Firewall & IPS/IDS- policy design, segmentation, east-west traffic control
- Network Access Control(NAC/802.1X, Cisco ISE, Aruba ClearPass)
- Secure SD-WANand the convergence of networking and security in modern enterprise WAN
- Cloud Security Networking- VPC security, cloud-native firewalling, private access patterns across AWS, Azure, and GCP
- PKI, certificate management, and encryption standards at scale
- Stay ahead of thevendor landscape(Palo Alto Networks, Zscaler, Cisco, Fortinet, Cloudflare, Netskope, etc.), providing clients with impartial, outcome-driven guidance.
- Act as atechnical escalation pointfor the wider network engineering team on security-related matters.
- Contribute tointernal capability development, helping upskill the team on emerging security technologies and methodologies.
Proposals, Pursuits & Deliverables- Lead thedevelopment of security proposals, RFP responses, and solution designs, from initial shaping through to final submission and presentation.
- Createhigh-quality client-facing deliverables- architecture documents, current-state assessments, roadmaps, business cases, and executive presentations - to a standard that reflects Accenture's positioning.
- Collaborate with sales and account teams toshape win strategies, define differentiated propositions, and structure commercial approaches that resonate with technical and business buyers alike.
- Be willing and able topersonally produce deliverableswhere required - this is not a role that delegates everything downward. The ability to create compelling, polished outputs directly is essential.
AI Proficiency & Innovation- LeverageAI tools and platforms(including generative AI) to accelerate the production of proposals, assessments, research, and client communications - demonstrating practical, day-to-day AI fluency.
- Advise clients on thesecurity implications of AI adoptionwithin their environments, including data exposure risks, access control considerations, and governance frameworks.
- Critically evaluate AI-generated outputs, understanding where AI adds velocity and wherehuman judgement and expertise remain essential- and communicate this distinction clearly to clients and colleagues.
- Champion thepragmatic use of AIwithin the network practice to improve team productivity and the quality of deliverables.
QualificationRequired Experience & QualificationsTechnical- Extensive hands-on and advisory experience acrossenterprise network security, with demonstrable depth in SASE, SSE, Zero Trust, and secure networking architectures.
- Strong understanding ofenterprise networking fundamentals(routing, switching, SD-WAN, WAN architecture) - able to engage credibly with network engineers, not just security practitioners.
- Experience designing or advising onlarge-scale security transformation programmesin complex, multi-site, or multi-cloud enterprise environments.
- Familiarity withcompliance and regulatory frameworksrelevant to enterprise clients (NIS2, DORA, ISO 27001, PCI-DSS, NIST CSF).
- Working knowledge of at leasttwo or more leading security vendorsat an architectural level (e.g. Palo Alto/Prisma, Zscaler, Cisco Umbrella/Duo, Fortinet, Netskope, Cloudflare).
Commercial & Communication- Proven ability towrite and present high-quality proposals and technical documentsto senior client audiences.
- Track record ofowning client relationshipsin a consulting, vendor, or managed services context - with demonstrable examples of account growth and client satisfaction.
- Ability tocommand technically complex rooms- earning credibility with engineers through substance, not authority.
- Commercially aware, with an understanding of how to frame security investments in terms ofrisk, compliance, and business valuerather than purely technical merit.
- Adaptable communication style - equally effective presenting to aCISO or a junior analyst, and able to read the room and adjust accordingly.
AI & Tools- Actively proficient withAI-assisted toolsfor content creation, research, and analysis (e.g. Microsoft Copilot, ChatGPT, Claude, or equivalent).
- Clear-eyed understanding of thelimitations and risksof AI-generated output, particularly in technical and client-facing contexts.
Qualifications- Degree in Computer Science, Information Security, Engineering, or equivalent practical experience.
- One or more of the following certifications highly desirable:
- CISSP, CISM, or CCSP
- CCIE Security
- Vendor certifications: Palo Alto PCNSE, Zscaler ZDTA/ZCCA, Cisco SCOR, Fortinet NSE 7/8
- Familiarity withSABSA, TOGAF, or equivalent security/enterprise architecture frameworksadvantageous.
The Ideal CandidateYou are not a pure architect who hands off to others, nor a pure account manager who relies on technical colleagues to fill the gaps. You occupy a rare middle ground - someone who has
earned their stripes technicallyand subsequently developed the judgement, communication skills, and commercial instincts to lead at a strategic level.
You are energised by variety. One day you are presenting a Zero Trust roadmap to a financial services CISO; the next you are deep in a proposal for a global manufacturing client's SASE migration; the following week you are in a workshop facilitating a threat modelling exercise with a team of network engineers.
You do not just direct - you do.You understand that AI is a tool, not a replacement for expertise, and you use it intelligently to move faster and produce better work - without compromising quality or accuracy.
Most importantly, you genuinely care about helping clients improve their
security posture, meet their compliance obligations, and protect what matters mostto their business.
