Capabilities

Practical security engineering across IT, OT, cloud, and security operations.

Six capability areas with one focus: turning findings and security technology into implemented, verified improvements.

Capability 01

Cybersecurity Assessment & Remediation

Assessments are only useful when they lead to change. Severnis assesses architecture, configuration, and risk with remediation in mind, then helps do the engineering work to close findings and verify the result.

Typical work

  • Architecture, configuration, and risk assessments scoped to your environment and requirements
  • Vulnerability identification, validation, and risk-based prioritization
  • Triage of existing audit, assessment, penetration test, and scanner findings
  • Practical remediation plans sized to available staff and change windows
  • Hands-on implementation assistance: hardening, configuration, access control, and logging
  • Retesting and evidence that demonstrates closure, including plan of action and milestones (POA&M) support

Outcomes

  • A prioritized remediation plan with clear ownership
  • Findings closed and verified by retest
  • Reduced configuration and exposure risk
Capability 02

IT/OT Security Integration

Connecting operational technology to business networks creates both value and exposure. Severnis assesses and strengthens IT/OT boundaries, communications, and systems with deliberate attention to availability, safety, and vendor support constraints.

Typical work

  • IT/OT architecture and boundary assessment, including communications-path review
  • Network segmentation review informed by ISA/IEC 62443 zone and conduit concepts
  • Firewall and ACL review, with controlled validation of enforced rules
  • Secure remote access review and design for staff and vendors
  • Passive traffic, flow, and industrial-protocol analysis to characterize communications
  • OT-aware vulnerability analysis and asset and vulnerability-management practices
  • Security assessment of PLCs, RTUs, HMIs, engineering workstations, historians, and industrial network infrastructure when specifically authorized
  • Logging and monitoring visibility for OT networks, followed by remediation and retesting

Outcomes

  • Documented boundaries and communications paths
  • Segmentation and remote access controls validated
  • OT-aware remediation, prioritized and retested
Capability 03

Security Technology Implementation & Integration

Vendors provide capable tools. Making them effective in a specific environment is separate work. Severnis helps deploy, configure, integrate, tune, and operationalize client-selected and third-party security technologies, then validates that they address the intended security objective.

Typical work

  • Architecture-fit review and deployment planning for selected technologies
  • Configuration, policy, and rule tuning to reduce noise and close coverage gaps
  • Telemetry and log integration with SIEM and monitoring workflows
  • Integration with existing identity, network, endpoint, and OT controls
  • Validation that the deployed control actually addresses its intended objective
  • Operational handoff: runbooks, ownership, and maintenance procedures

Outcomes

  • Technology deployed to intended effect
  • Resulting findings triaged and closed
  • Operations teams able to run what was deployed
Capability 04

Microsoft & Cloud Security

Many organizations already own substantial security capability through Microsoft and cloud licensing. Severnis helps configure it correctly, connect it to useful telemetry, and harden it in practical steps.

Typical work

  • Microsoft 365 security configuration review and hardening
  • Identity and access controls: Conditional Access, MFA, and privileged access
  • Microsoft Sentinel onboarding, data connectors, and KQL-based detections and hunting
  • Security telemetry integration and alert workflow design
  • Azure and cloud configuration review informed by CIS Benchmarks and CISA SCuBA guidance
  • Hands-on implementation of prioritized hardening changes

Outcomes

  • Licensed security capabilities enabled and tuned
  • Identity controls enforced consistently
  • Telemetry that supports detection and investigation
Capability 05

Security Automation

Manual security work drifts and doesn’t scale. Severnis builds practical automation that reduces repetitive tasks, correlates evidence across tools, and fits into existing operations.

Typical work

  • Security workflow automation for repetitive analyst and administrative tasks
  • Evidence and telemetry correlation across security and IT tools
  • Detection content and response playbooks for common actions
  • Custom scripting and API integration where off-the-shelf options fall short
  • Automated evidence collection for audits and control assessments
  • Configuration drift detection for security-relevant settings

Outcomes

  • Less repetitive manual work
  • Faster, more consistent response actions
  • Evidence produced on demand
Capability 06

Secure AI Integration

Where AI-assisted workflows make sense, Severnis helps integrate them with the same discipline applied to any other system: defined data handling, clear trust boundaries, and human review of results.

Typical work

  • Assessment of where AI-assisted workflows fit security and operational processes, and where they do not
  • Data-handling and trust-boundary review before sensitive information reaches any AI service
  • Local or private processing patterns where data sensitivity or requirements demand them
  • Human-reviewed, AI-assisted security automation with accountable decision points
  • Access control, logging, and monitoring for AI-enabled tools

Outcomes

  • Defined data-handling rules for AI use
  • Sensitive data kept within approved boundaries
  • Human accountability for AI-assisted outputs

Engagement models

Scoped to the outcome you need.

Engagements are defined around specific deliverables and validation criteria, and can be structured to fit direct, subcontract, or teaming arrangements.

Model A

Assessment to remediation

A scoped assessment followed directly by the engineering work to close and retest priority findings.

Model B

Remediation support

Focused effort to close an existing backlog of audit, assessment, or scan findings.

Model C

Technology integration

Deployment, tuning, and validation of a selected security technology, boundary, or control set.

Model D

Ongoing engineering

Recurring technical capacity for security improvements, working alongside your team.

Reference frameworks

Informed by recognized practice.

Work may be informed by recognized cybersecurity and operational-technology security practices, including NIST Cybersecurity Framework 2.0, NIST SP 800-82 Rev. 3, CISA Cross-Sector Cybersecurity Performance Goals, and applicable ISA/IEC 62443 concepts. Other references, such as CIS Controls and Benchmarks or CISA SCuBA baselines, may apply depending on the environment.

  • NIST CSF 2.0
  • NIST SP 800-82 Rev. 3
  • CISA CPGs
  • ISA/IEC 62443 concepts
  • NIST SP 800-53
  • CIS Controls & Benchmarks
  • CISA SCuBA
  • Texas Cybersecurity Framework

Reference frameworks inform the approach. They do not indicate certification, formal conformance, or endorsement, and engagements are not compliance assessments unless explicitly scoped that way.
