Network Security Assessment Services
Build a clearer view of network exposure and remediation priorities. SignX supports external, internal, wireless and on-site network assessments, with owned targets, access paths, safety controls and exclusions agreed before work begins.
- Clarify exposure across approved network environments
- Help infrastructure teams prioritize configuration and access risks
- Support change planning with documented assessment boundaries
For teams responsible for changing infrastructure
The assessment is intended for organizations that need a defined, time-bound view of reachable services and network control boundaries. SignX supports remote security assessments for international clients, subject to technical feasibility and agreed engagement scope. On-site network assessments are available depending on location, travel arrangements and the project quotation.
Infrastructure changes
Organizations preparing significant platform, hosting or connectivity changes.
Internet exposure
Businesses that need a defined view of agreed internet-facing systems and services.
Internal segmentation
Teams reviewing administrative access and trust boundaries between approved network zones.
Connected environments
Companies integrating offices, cloud workloads or acquired systems under one operating model.
A clearer basis for infrastructure risk decisions
A scoped network assessment helps technical owners understand reachable services and control boundaries while keeping operational risk and untested systems visible.
Exposure visibility
Document observations across the external, internal or wireless boundary selected for review.
Remediation priorities
Connect confirmed findings to affected targets and practical configuration work.
Operational context
Give infrastructure owners a time-bound view for change, integration and review planning.
Network assessment modes
SignX's in-house security team supports external, internal, wireless and on-site assessments. Credentialed testing and controlled exploitation are not included in this service.
External assessments
Review of client-owned internet-facing ranges, domains and reachable services named in scope.
Internal assessments
Review of approved internal network zones and access paths within the client-authorized boundary.
Wireless assessments
Review of approved wireless environments and boundaries under written client authorization.
On-site assessments
Assessment performed at an approved client location under agreed access, safety and operational rules.
Delivered by SignX's in-house security team
Network assessment activities
These activities are available capabilities. Approved ranges, access, fragile systems, wireless boundaries and on-site safeguards must be documented for each engagement.
Reachable services
Assessment of authorized network services reachable within the approved boundary.
Network configuration
Assessment of security-relevant network configuration.
Patch and version exposure
Assessment of patch and version exposure observable within scope.
Administrative access
Security review of approved administrative-access paths without implying credentialed network testing.
Network segmentation
Assessment of approved segmentation boundaries and reachable paths.
Available activities are selected in the written scope and quotation
Exposure and configuration risk across agreed network zones
The final scope determines what is tested. These areas show the kinds of network risk an authorized assessment may examine.
Reachable services
Unnecessary externally accessible services and weak exposure controls.
Configuration and patching
Missing patches, insecure defaults and service settings that increase risk.
Administrative access
Exposure and security observations for approved administrative-access paths, without implying credentialed testing.
Segmentation
Trust and routing gaps between network zones selected for review.
Legacy systems
Unsupported technologies, default settings and older protocols within the approved range.
Asset visibility
Incomplete knowledge of systems and services reachable inside the authorized boundary.
Target ranges, access and prohibited actions agreed first
External, internal, wireless or on-site workstreams can be selected during scoping. Target ownership, access paths, fragile systems, testing windows and emergency contacts are documented. Credentialed assessment, controlled exploitation and cloud control-plane testing are not included.
External boundary
Owned internet-facing ranges, domains and services included in the assessment.
Internal, wireless and on-site boundary
Approved network zones, wireless environments, access paths and client locations named in the engagement.
Safety controls
Fragile systems, testing windows, escalation contacts and permitted non-destructive assessment activity.
Explicit exclusions
Credentialed assessment, controlled exploitation, social engineering, denial of service, cloud control-plane review and unauthorized third-party targets are not included.
From ownership confirmation to prioritized remediation
A practical sequence keeps authorization, fragile systems and operational risk visible throughout the assessment.
Confirm ownership
Record target ranges, exclusions and safe-test rules.
Establish access
Prepare approved access and asset context.
Discover and assess
Evaluate services within the authorized boundary.
Validate
Confirm findings using the least disruptive approved method.
Report and read out
Deliver prioritized findings and configuration guidance.
Agree retesting
Retesting arrangements, including scope, timing and any applicable fees, are agreed as part of the project quotation.
Standard assessment deliverables
Seven standard deliverables for each scoped assessment
Severity model: CVSS 4.0 + Business Context. CVSS v4.0 is applied to technical vulnerabilities when it is suitable and supported by the available evidence. Technical severity, affected assets and exploit conditions are recorded separately from business impact, asset criticality and remediation priority. When CVSS is unsuitable or the evidence is insufficient, the report uses a reasoned qualitative severity and clearly states its basis.
- Executive summary for business and technical stakeholders
- Documented assessment scope, exclusions, environments, dates and testing limitations
- Validated technical findings with appropriately redacted supporting evidence
- Severity ratings and business-risk prioritization using the approved CVSS 4.0 + Business Context model where applicable
- Actionable remediation recommendations
- Technical assessment report and client readout session
- Retesting arrangements documented according to the project's agreed scope and quotation
Questions before a network assessment
The answers separate discovery, assessment and controlled validation while keeping operational safety decisions in the written scope.
Which network assessment modes does SignX support?
SignX's in-house team supports external, internal, wireless and on-site network assessments. The proposal must identify the selected workstreams, authorized targets and location or access requirements.
Can internal and external networks be assessed together?
Yes, they can be separate workstreams in one engagement when ownership, access, ranges, safety controls and reporting boundaries are agreed. Credentialed testing and controlled exploitation are not included.
Does this include cloud security?
Only client-owned network-accessible targets explicitly listed in scope. Cloud identity, account configuration and control-plane review are not included in this service.
Will the assessment disrupt systems?
Testing should be planned to reduce operational risk, but no assessment is risk-free. Fragile systems, prohibited techniques, maintenance windows and incident contacts must be agreed before testing.
Connect network findings to infrastructure engineering
Existing SignX software and infrastructure services remain the primary offer. These links support remediation context without implying bundled assessment work.
