Security
Data and Cyber Security Services
Find weaknesses before attackers do, detect threats early, respond decisively and protect the applications, cloud environments and data your business runs on.
Security Built into Every Layer of Your Business
Attackers no longer need a sophisticated zero-day to cause damage. A misconfigured storage bucket, an unpatched VPN appliance, a leaked API key in a code repository or a convincing phishing email is often enough. At the same time, cloud adoption, remote work, SaaS sprawl and AI tools have multiplied the number of identities, endpoints and data stores that need protecting, while customers and regulators expect evidence that their information is safe.
Hanoi Technology helps you build a security program that matches your real risk. We identify vulnerabilities across infrastructure, cloud and applications, set up detection and monitoring that surfaces genuine threats, prepare and support your incident response, and implement protective controls for identities, endpoints, applications and data. Because we also build software and data platforms, we embed security into engineering rather than adding it at the end.
The Challenge
Security Challenges Organizations Face Today
Security teams are asked to cover more ground with limited people and budget.
An Expanding Attack Surface
Cloud workloads, SaaS applications, APIs and remote devices create assets that are often unknown to the security team and therefore unprotected.
Too Many Alerts, Too Little Context
Security tools generate thousands of alerts, and without tuning and correlation the important signals are lost in noise.
Unprepared Incident Response
When an incident happens, unclear roles, missing logs and untested playbooks turn a contained event into a prolonged outage.
Skills and Capacity Gaps
Many organizations cannot staff specialists for cloud security, detection engineering and forensics, leaving gaps in coverage.
Business Value
What a Strong Security Program Delivers
Reduced Likelihood of Breaches
Prioritized remediation of exploitable weaknesses and hardened configurations remove the easiest paths for attackers.
Faster Detection and Containment
Tuned detection rules and practiced response procedures reduce the time attackers have inside your environment.
Protected Customer and Business Data
Encryption, access controls and data loss prevention keep sensitive information where it belongs.
Evidence for Customers and Auditors
Documented controls and test results support security questionnaires and frameworks such as ISO/IEC 27001, SOC 2 and NIST CSF.
Secure Software Delivery
Security testing in development pipelines catches flaws before release, when they are cheapest to fix.
Business Resilience
Tested backups, recovery plans and response playbooks keep critical operations running when something goes wrong.
Security Is a Continuous Practice
Threats, technologies and your own environment change every week. Effective security is not a single audit but a cycle of identifying risks, protecting assets, detecting attacks, responding and recovering, which mirrors the functions of the NIST Cybersecurity Framework 2.0. We help you establish that cycle and keep it running.

Use Cases
Security Use Cases
Examples of the security challenges we help address.
Preparing for Enterprise Customer Reviews
A SaaS company tests its application, closes high-risk findings and documents controls before a major customer security assessment.
Securing a Cloud Migration
A business moving to AWS or Azure reviews landing zone configuration, identity design and logging before production workloads go live.
Building a Detection Capability
A mid-size company centralizes logs in Microsoft Sentinel and implements tuned detection rules for its most relevant attack techniques.
Ransomware Readiness
An organization hardens backups, segments networks and rehearses a ransomware scenario with leadership and IT.
Protecting Customer Data in Fintech
A fintech platform implements encryption, tokenization and fine-grained access controls for sensitive financial data.
DevSecOps for Product Teams
A software team adds automated security checks to its pipelines so vulnerabilities are caught in pull requests rather than after release.

Security FAQ
Where should we start if our security program is immature?
Start with an understanding of your critical assets and the most likely threats, followed by basics that block common attacks: multi-factor authentication, patching of internet-facing systems, secure cloud configuration, endpoint protection, tested backups and centralized logging. A short assessment against a framework such as NIST CSF 2.0 helps prioritize. We focus first on quick wins that reduce real risk, then build a roadmap for detection, response and governance.
Do you provide 24/7 security monitoring?
We help design, implement and tune detection and monitoring capabilities, and we can support monitoring as part of a managed service with agreed coverage hours and escalation paths. For organizations that need round-the-clock coverage, we can also help integrate a specialized managed detection and response provider and make sure their alerts and playbooks fit your environment. We agree the exact scope and service levels with you during planning.
How do you handle access to our systems during testing?
All testing is performed under a written scope and rules of engagement that define targets, timing, techniques and contacts. We use named accounts with the minimum privileges required, follow your security policies and log our activities. Sensitive findings are shared through secure channels only. For production systems, we agree testing windows and safeguards to avoid disruption, and we stop immediately if unexpected impact occurs.
Can you help us prepare for ISO 27001 or SOC 2?
Yes. We assess your current controls against the requirements of the framework, identify gaps and help you implement missing technical controls, policies and evidence collection. We do not issue certifications or audit reports ourselves; those come from accredited certification bodies or independent auditors. Our role is to help you become ready, so the formal audit runs smoothly and with fewer findings.
What drives the cost of security services?
The main drivers are the number and complexity of systems in scope, the depth of testing required, the number of log sources and detection use cases, the need for monitoring coverage outside business hours, and any security tooling licenses. A focused assessment or penetration test is a defined project; ongoing detection and protection are typically delivered as a dedicated team or managed service. We provide transparent estimates after an initial scoping call.
How do you work with our existing IT and security staff?
We work as an extension of your team. Your staff keep ownership of decisions and systems, while we provide specialist skills, extra capacity and documentation. Every engagement includes weekly written progress updates, clear findings with remediation guidance and knowledge transfer so improvements are sustainable. We can also coordinate with your other vendors, such as managed service providers or software suppliers, when remediation involves them.
