Cybersecurity for complex IT and OT environments
Senior specialists, strengthened by AI
Defence and government organisations depend on trust, resilience and the protection of sensitive information. Ministries, executive agencies, municipalities, security services and defence-related organisations process confidential data and rely heavily on digital processes. One vulnerability in identity, line-of-business applications, cloud, SaaS, APIs or network segmentation can directly affect public services, national security and public trust. Cybersecurity in defence and government therefore requires an approach that accounts for confidentiality, supply chains and operational continuity.
Government and defence environments use case-management systems, line-of-business applications, base registries, communication tools, mobile workstations, external supply-chain partners and cloud platforms. These systems are often tightly connected. A vulnerability in one domain can affect access to confidential data, decision-making or public service delivery. The attack surface grows through SaaS, cloud, identity federation, API integrations and data exchange between organisations. Legacy systems also often remain in use longer because line-of-business applications depend on specific versions. This creates risk at the boundary between old and new technology, especially where administrative rights, integrations and network segmentation are not configured precisely.
DeepBlue helps defence and government organisations determine which risks are actually exploitable. Not only from a policy or compliance perspective, but from an attacker’s perspective. We examine how an attacker gains access, which privileges can be expanded, which systems can be reached and what impact is possible on processes and information. AI and tooling support analysis, correlation and efficiency. The core remains technical expertise, attacker insight and demonstrable impact. Penetration tests make these risks concrete by validating attack paths in a controlled way and translating them into technical assurance, remediation priority and executive-grade insight.
DeepBlue is CCV Pentest certified
Penetration testing in defence and government must prove more than technical vulnerabilities. The key question is which vulnerabilities are actually exploitable and what impact they can have on confidential data, public services and continuity. DeepBlue therefore tests from realistic attack paths. We examine identity environments, line-of-business applications, case-management systems, cloud platforms, APIs, network segmentation, external infrastructure and reachability of critical systems. We assess not only access, but also privilege escalation, lateral movement, data access, logging, detection and recovery options.
Our penetration tests are manual, deep and controlled. Senior specialists with experience in complex IT and OT environments execute the work. Tooling and AI support the analysis, but do not determine the outcome. The focus is on demonstrable impact, clear risk assessment and concrete remediation priority. Findings are mapped with CVSS, so technical teams can remediate precisely and executives understand where the greatest risk sits. DeepBlue is CCV Pentest certified and delivers independent, reliable and practical penetration test reports for defence and government organisations that need technical assurance over digital resilience.
Ransomware is one of the most critical threats to defence and government organisations. Attackers gain administrative privileges, sabotage backups, evade detection and encrypt systems. Outages in line-of-business applications, communications or public services directly disrupt processes, trigger emergency procedures and increase risks for citizens and security.
Identity is a primary attack surface in defence and government. Attackers abuse weak MFA, shared accounts, excessive privileges, service accounts and insufficiently controlled external access. With many user groups, external parties and supply-chain partners, one account can provide access to multiple critical systems.
Web applications, citizen portals, case-management systems and line-of-business applications process confidential data and often integrate with underlying systems and base registries. Vulnerabilities such as broken access control, IDOR, weak session security and insufficient input validation can give unauthorised access to data or internal functions.
Data exchange between government bodies, supply-chain partners and external services runs through integrations and APIs. Attackers look for weak authentication, excessive authorisations, manipulable messages and insufficient validation between systems. The main risk sits in the connection between internal systems and external chains.
Defence and government organisations increasingly use cloud and SaaS for collaboration, data processing and supply-chain exchange. Risks arise from misconfigured tenants, public storage, excessive privileges, weak logging and insecure integrations. One cloud error can expose confidential data at scale.
Defence and government organisations depend heavily on software suppliers, technology partners, managed service providers and outsourced services. Attackers abuse these trust relationships: remote administration, VPN access, shared accounts, weak monitoring and overly broad access to management portals.
In government and defence environments, the greatest risk often lies in the connection between systems. A vulnerable portal can provide access to an internal API. An unnecessarily reachable management system can enable lateral movement. A service account with excessive privileges can provide access to confidential data. DeepBlue therefore looks not only at individual vulnerabilities, but at the path an attacker can follow from initial access to privilege escalation, data access, process disruption and potential impact on critical systems.
These attack paths show where technical measures are immediately required and where structural improvement is necessary. Examples include stronger segmentation between line-of-business environments and office automation, tighter privileges on identity and service accounts, hardening of external access, restriction of management interfaces and improved logging and detection. DeepBlue translates findings into technical detail, remediation priorities and practical measures. This creates one clear view for executives, security, IT operations and those responsible for continuity.
Bewustwording en vaardigheden bepalen hoe goed medewerkers dreigingen herkennen en erop reageren. DeepBlue verzorgt phishing-simulaties, awareness-trainingen en technische oefeningen voor SOC- en IT-teams. De inhoud sluit aan op uw processen, rollen en realistische aanvalsscenario’s.
Red Teaming is relevant voor organisaties die hun detectie, respons en weerbaarheid tegen realistische aanvalspaden willen testen. De focus ligt op doelgerichte scenario’s, zoals toegang tot gevoelige data, laterale beweging naar bedrijfskritische systemen of omzeiling van detectie.
Een Managed SOC ondersteunt organisaties bij continue detectie, triage en opvolging. De waarde zit in use cases die aansluiten op echte aanvalspaden, zoals identity abuse, verdachte toegang tot gevoelige data, laterale beweging en afwijkend gedrag in cloudomgevingen.
Bij incidenten is snelheid cruciaal. DeepBlue onderzoekt hoe een aanvaller toegang kreeg, welke systemen zijn geraakt, welke data mogelijk is benaderd en welke maatregelen nodig zijn om uw bedrijfsvoering veilig te herstellen.
CISO as a Service helpt organisaties bij securitystrategie, risicosturing, leveranciersbeheersing, incidentvoorbereiding en technische prioritering. De focus ligt op uitvoerbare maatregelen die passen bij uw processen en beschikbare capaciteit.
Fysieke toegang kan digitale impact hebben. Denk aan werkplekken, balies, netwerkpoorten, kantoren, serverruimtes en leverancierszones. Een fysieke weerbaarheidstest toont waar fysieke beveiliging, menselijk gedrag en cyberrisico elkaar raken.
