Infrastructure security
Cube Cyber manages the security of your network and server infrastructure as an ongoing service, firewall policy and rule governance, system hardening, secure configuration management and patching oversight. Architecture decides how secure an environment can be; operations decides how secure it stays, and configuration drift is the quiet force that reopens what good design closed. This service exists to stop the drift.
Talk To Us About Infrastructure Security
Infrastructure security erodes in slow motion:
The strongest entry points follow an architecture or uplift investment, protecting new segmentation and hardened builds from day-two drift, or an audit and assessment cycle that flagged configuration weaknesses the internal team has no capacity to keep resolving. Steady-state triggers are just as valid: a firewall estate due for consolidation or migration, an Essential Eight program needing its hardening and patching strategies operated rather than just assessed, and infrastructure teams stretched thin who need the security layer of their work carried by specialists.
Core capabilities & deliverables
Firewall and network policy management
Governed change management, periodic rule-base review and cleanup, and policy kept aligned to your segmentation architecture, across the firewall estates our clients run, including Fortinet and Cisco platforms.
System hardening management
Hardened baselines established for servers and network devices, aligned to recognised benchmarks and Essential Eight hardening strategies, then monitored for drift and remediated when reality moves off the standard.
Secure configuration monitoring
Continuous comparison of running configuration against approved baselines across the estate, catching the expedient change, the disabled control and the unauthorised exception while they are still small.
Patching oversight and assurance
Independent oversight of patch deployment against Essential Eight timeframes, exceptions tracked with owners and compensating controls, and the exposure window reported honestly, assurance, not just automation.
Vulnerability remediation support
Hands-on engineering support to close infrastructure findings from testing and vulnerability management, the fixing capacity that determines whether findings become improvements or wallpaper.
Change and exception governance
Security review within your change process for infrastructure changes, and a managed exception register, so temporary risk decisions stay temporary and visible.
The service runs on the managed practice operating model:
Onboard
Estate discovery, baseline definition and rule-base assessment, establishing what good looks like for this environment.
Tune
Initial cleanup and hardening: rule-base reduction, baseline enforcement, exception triage, the debt paid down.
Operate
Ongoing policy management, drift monitoring, patching oversight and remediation support, in your change rhythm.
Improve
Quarterly posture reviews: rule-base health, drift trends, patch performance and exception ageing, reported in terms a board can read.
Hardening aligns to recognised benchmarks and ASD guidance, patching oversight to Essential Eight strategies and timeframes, and the whole service to ISO 27001 operational control objectives, integrating with our architecture practice, which designs what this service preserves, and our SOC, which watches what this service maintains.
ISO 27001Frequently asked questions
No, it takes the security layer of their load. Your team keeps platform ownership and daily operations; we carry firewall policy governance, hardening, drift management and patching assurance (your team continues to do the patching), the work that is always important and never urgent, until it is. The division of duties is agreed at onboarding and revisited as your team evolves.
Yes, it is one of the most common starting engagements. Rules are analysed against actual traffic, unused and shadowed rules identified, owners traced where they exist, and reduction executed in staged, reversible changes through your change process. Rule bases typically shrink dramatically, and what remains is documented and owned.
Directly: several strategies, patch applications, patch operating systems, user application hardening, restrict administrative privileges in part, are operational disciplines, not projects. This service operates them continuously and generates the evidence maturity assessments require, the difference between claiming a level and holding one.
Full visibility, it is your infrastructure. All changes flow through your change management, baselines and exceptions live in shared registers, and quarterly reporting shows posture trends honestly, including the uncomfortable parts. The service model is transparency with accountability, not a black box.
Yes, with OT rules applied: baselines and changes planned with the engineers who own uptime, monitoring by passive methods, and patching decisions led by compensating controls where patching is not realistic, more than 10 years of OT experience shapes what we will and will not touch, and when.
A materially smaller and documented firewall rule base, systems measurably on baseline with drift trending down, patch exposure windows reported honestly and shrinking, and an exception register where every entry has an owner and an expiry. None of it is glamorous; all of it is what keeps architecture true.
Yours, always, though we also run our own internal CAB for the work we deliver. Infrastructure changes are proposed, documented and executed inside your change process, with our engineers presenting at your CAB where wanted, and emergency changes following your emergency path. The service adds security discipline to your change rhythm; it never creates a second, parallel one.
