Overview
Network security is no longer a one-time firewall purchase. Sri Lankan organisations now run cloud applications, remote users, guest networks, CCTV, IP phones, branch links, and internet-facing services. Without a clear security design, the firewall becomes a list of rules no one fully understands. OneAccess helps organisations assess, implement, and operate network security controls that match the business risk and the actual environment.
Where this helps
Our work can begin with an existing firewall review or a new deployment. We examine policy structure, exposed services, NAT rules, VPN access, administrator accounts, firmware, subscriptions, logging, backup, segmentation, and whether security features are actually enabled. Many environments have capable hardware but weak policy discipline. The goal is to turn the firewall into a controlled security boundary rather than a box that was installed and forgotten.
What OneAccess delivers
Implementation may include next-generation firewall configuration, IPS, application control, web filtering, SSL inspection where suitable, site-to-site VPN, secure remote access, VLAN segmentation, guest isolation, management access hardening, logging, reporting, and documentation. We also help teams understand trade-offs, such as performance impact, user experience, certificate handling, and how strict policies should be introduced without breaking operations.
Local operating context
OneAccess is useful for organisations that need practical security progress without overwhelming the business. We focus on clear policy intent, measurable risk reduction, and supportable operations. Whether you need a firewall refresh, a branch security design, VPN cleanup, or a stronger network security baseline, the outcome should be a safer environment that your team can understand and maintain.
Best next step
Share your current environment, locations, users, and main pain points through the contact form. OneAccess will review the requirement and recommend a practical first conversation, assessment, or implementation scope.
Who this service is for
A firewall is only useful when policy, identity, routing, logging, firmware, and operational ownership are understood. OneAccess helps turn network security from a device purchase into a supportable security boundary.
- Businesses replacing or reviewing an existing firewall
- Teams that need clearer firewall policy, VPN access, logging, and segmentation
- Organisations concerned about exposed services, weak remote access, or unmanaged security rules
Outcomes to expect
- Firewall and network security scope aligned with business risk and actual traffic flows
- Cleaner policy structure for users, branches, guests, vendors, and administrators
- Documentation and handover that makes future rule changes safer to manage
What is included
Firewall assessment
Review policies, NAT, VPN, logging, firmware, licensing, and exposure before recommending changes.
NGFW implementation
Configure security profiles, application controls, IPS, web filtering, SSL inspection where appropriate, and reporting.
Network segmentation
Separate users, servers, guests, IoT, CCTV, and administrative access to reduce lateral movement risk.
Operational handover
Document policy intent, admin access, backup, monitoring, and incident response contacts.
Why teams choose this
- Reduced external and internal attack surface
- Cleaner firewall policy management
- Better VPN and remote access control
- Security rules documented by purpose
- Practical vendor-neutral recommendations
- Local implementation and support
How OneAccess delivers this service
Review current risk
Check exposed services, policy structure, VPN access, administrator accounts, firmware, subscriptions, logging, backups, and segmentation gaps.
Implement controls
Configure agreed firewall, VPN, segmentation, filtering, logging, and management-access controls with practical rollout planning.
Document and operate
Record the policy intent, backup configuration, handover notes, and follow-up risks so security remains supportable.

Scope notes
Security features depend on device capability, valid subscriptions, performance headroom, firmware support, certificate handling, and user impact. OneAccess does not publish unsupported guarantees of total protection.
Common questions
Can OneAccess review an existing firewall before replacing it?
Yes. A review can identify policy, firmware, logging, VPN, segmentation, backup, and subscription gaps before deciding whether replacement is necessary.
Does network security include VPN and remote access?
It can. VPN and remote access are often part of the security boundary, but dedicated remote-access design is handled in more detail under the VPN service.
Can strict security controls affect users?
Yes. Filtering, SSL inspection, VPN rules, and segmentation can affect user experience, so rollout should be staged and documented.
