Networking

Segmentation and inspection that stop an attack from spreading.

Next generation firewalls, network segmentation and microsegmentation, intrusion prevention, DDoS protection and firewall policy management.

Sound familiar

Where this usually starts.

When an attacker gets in, the network decides how far they get. Flat networks let ransomware reach every server from one compromised laptop; segmented networks contain it. We design segmentation from how systems actually communicate, deploy and tune next generation firewalls and intrusion prevention, protect internet-facing services from denial of service, and keep firewall rules reviewed so they never accumulate into a policy nobody understands.

Tick the ones that sound like your situation.

Scope

What is included.

  • Segmentation design

    Zones and rules derived from real traffic and business needs.

  • Microsegmentation

    Workload level controls for data centers and cloud.

  • Firewalls

    Next generation firewalls deployed, configured and kept current.

  • Intrusion prevention

    Inspection tuned to your traffic.

  • DDoS protection

    Defenses for internet-facing services and links.

  • Rule review

    Firewall policies cleaned up and reviewed on a schedule.

Reference architecture

Networks designed from the traffic up.

Network security appears twice in the networking architecture: DDoS protection at the edge, and segmentation inside the data center that decides how far an attacker can move.

What this service delivers here

  • DDoS protection

    Absorbs volumetric attacks before they reach your links.

  • Segmentation

    Firewalls and policy that decide how far anything can move.

Walk through every flow in Networking

Before you start

Decisions to settle early.

  • Network firewalls or microsegmentation

    Zone firewalls are simpler; workload-level controls contain more. Most estates need zones first and microsegmentation where risk is highest.

  • Which firewall platform

    Your existing platform may be adequate once its rules are cleaned up. Replacement is justified by capability, not habit.

  • Cloud or on-premise DDoS protection

    Large attacks need cloud scrubbing; smaller ones can be handled at the edge. Exposure decides the mix.

Approach

How the work runs.

  1. Map

    Traffic and critical assets

  2. Design

    Zones and policies

  3. Enforce

    Firewalls and segmentation deployed

  4. Review

    Rules audited on a schedule

Commercials

How it is bought.

  • A fixed-fee assessment

    We map real traffic between systems, review firewall rule sets and identify critical assets. You receive the findings, a segmentation outline and a fixed price.

  • A fixed-price build

    Segmentation design and enforcement in stages, firewall and intrusion prevention deployment, DDoS protection and a rule cleanup, for the scope agreed.

  • Running it afterwards

    Rule reviews and firewall operations can then run monthly or quarterly under our service, or be handed to your team.

Start with the assessment.

Scope an assessment

Worked example

A flat network and an old rule set.

Say a manufacturer's office laptops, production line controllers and servers share one flat network, and its firewall holds rules built up over many years that nobody can explain.

  1. Map

    We record real traffic between systems for long enough to see the rare flows, and identify the assets an attacker would most want.

  2. Design

    Zones separate the office, production and server networks, and the rules between them allow only the flows the business needs.

  3. Enforce

    Segmentation is applied in stages with monitoring, so a missed dependency is caught and fixed before it stops a production line.

  4. Review

    The old rule set is cleaned up with the rule owners, and reviews are scheduled so it does not grow back.

At the end, a compromised laptop can no longer reach the production line, every firewall rule has an owner and a reason, and the rule set is reviewed rather than inherited.

An illustration

An illustration, not a client account.

Where it goes wrong

What we design out.

  • Rules from assumptions

    Segmentation designed on paper breaks applications. Rules come from observed traffic.

  • Enforcing on day one

    Blocking before monitoring finds missed dependencies the hard way. Rules run in monitoring mode first.

  • Rule sets that only grow

    Firewalls accumulate rules nobody can explain. Reviews remove what has no owner.

Outcomes

What it changes.

  • Attacks contained

    Segmentation stops a compromise in one zone from reaching the rest.

  • Rules you can explain

    Every firewall rule has a reason and an owner.

  • Services that stay up

    DDoS protection keeps internet-facing systems available under attack.

How you will know it is working

  • A compromised laptop cannot reach critical systems.
  • No firewall rule exists without someone accountable for it.
  • Internet-facing services stay up under attack traffic.
  • Rule reviews happen on schedule.

You keep

What you have at the end.

The team

Who you work with.

  • Security architect

    Designs segmentation from observed traffic and critical assets.

  • Firewall engineers

    Deploy and tune firewalls, intrusion prevention and DDoS defenses.

  • Rule review analyst

    Cleans up rule sets and runs scheduled reviews with rule owners.

What we need from you

  • Access to firewalls and network flow data.
  • A list of critical systems and their owners.
  • Maintenance windows for enforcement.
  • Owners for existing firewall rules, where known.

When something slows down, you see where, and so do we.

Questions

Questions we get asked.

Where should segmentation start?

Around the assets that would hurt most if they were reached: domain controllers, backups, payment and production systems. Separating those from user networks delivers most of the benefit early.

Is microsegmentation worth it?

For data centers and cloud estates with many workloads, often yes. It controls traffic between individual workloads, which stops attackers moving sideways once they are inside.

Can you clean up an old firewall rule set?

Yes. We analyze rule usage and traffic, remove unused and overly broad rules in stages with rollback, and document the reason for every rule that remains.

Do we still need firewalls with Zero Trust?

Yes. Zero Trust reduces reliance on the network perimeter, but segmentation and inspection still limit what an attacker can reach, and they give defenders visibility.

How do you segment a network without breaking applications?

By basing the rules on observed traffic rather than assumptions, applying them first in a monitoring mode that logs what would be blocked, and moving to enforcement in stages. Dependencies the monitoring reveals are reviewed with their owners before anything is blocked.

Can industrial and operational technology networks be segmented safely?

Yes, with care. Industrial systems often cannot be patched and may not tolerate scanning, so they are isolated in their own zones, with tightly controlled paths to the office network and to vendors, and monitored passively. Changes are planned with the engineers who run the plant.

What does intrusion prevention add to a firewall?

A firewall decides which connections are allowed; intrusion prevention inspects the traffic inside allowed connections for known attacks and exploit attempts, and blocks them. It is tuned to your traffic, because untuned it either blocks legitimate use or is left in a mode that only logs.

How do you protect against denial of service attacks?

With layered defenses: provider or cloud scrubbing for large volumetric attacks, protection for web applications against floods at the application layer, and capacity and rate limits at your edge. The right mix depends on which services face the internet and what an outage of each would cost.
