Security

Cyber Protection Services

Put the right preventive controls around your identities, devices, cloud workloads, applications and data, so common attacks fail and serious ones are contained.

Make Your Organization a Hard Target

Most breaches still begin with familiar weaknesses: a stolen password without multi-factor authentication, an over-privileged account, an unmanaged laptop, a cloud resource exposed to the internet or backups that attackers can delete along with production data. These gaps persist not because the fixes are unknown, but because protective controls are spread across many tools, configured inconsistently and rarely reviewed as the environment changes.

Hanoi Technology designs and implements layered protection based on zero trust principles. We harden identity and access, secure endpoints and email, apply secure baselines to cloud environments, protect sensitive data with classification, encryption and loss prevention, and make backups resilient to ransomware. Because we also build applications, we help your products protect themselves through secure architecture, secrets management and API security.

The Challenge

Why Protective Controls Fall Short

Even organizations with many security tools often leave critical gaps.

Identity Is the New Perimeter

Remote work and SaaS mean an attacker with valid credentials can reach most systems, yet MFA, conditional access and privileged access controls are often incomplete.

Inconsistent Cloud Configuration

Multiple accounts, subscriptions and teams lead to drifting configurations, open storage, broad permissions and missing encryption.

Unprotected Sensitive Data

Without classification and data loss prevention, confidential information spreads into email, file shares, SaaS tools and AI assistants.

Backups That Will Not Survive an Attack

Backups connected to the same identity domain or network can be encrypted or deleted by ransomware operators.

Business Value

What Strong Cyber Protection Delivers

Fewer Successful Attacks

Phishing-resistant authentication, hardened devices and secure configurations block the most common intrusion paths.

Limited Blast Radius

Least privilege, segmentation and conditional access contain an attacker who does get in.

Protected Sensitive Information

Classification, encryption and data loss prevention keep confidential data under control.

Ransomware Resilience

Immutable, isolated and tested backups let you recover without paying a ransom.

Secure Products

Applications built with secure design, secrets management and API protection reduce risk for your customers.

Demonstrable Security Posture

Consistent baselines and posture scores give leadership, customers and auditors clear evidence of protection.

Assume Breach, Design for Containment

Zero trust is not a single product. It is a set of principles: verify explicitly, grant least privilege and assume breach. Applied consistently to identities, devices, networks, applications and data, these principles turn a single compromised account from a crisis into a contained event.

Use Cases

Cyber Protection Use Cases

Examples of protection projects that reduce real risk.

Zero Trust Access for a Distributed Workforce

A company replaces broad VPN access with conditional, device-aware access to applications for remote employees.

Microsoft 365 Security Hardening

An organization enables phishing-resistant MFA, tightens sharing settings and deploys sensitivity labels and DLP.

Secure Multi-Account Cloud Foundation

A scale-up builds a governed AWS or Azure landing zone with guardrails, centralized logging and encryption by default.

Protecting Financial Data in a Fintech App

A fintech platform tokenizes payment data, manages secrets in a vault and enforces least privilege for internal tools.

Ransomware-Resilient Backups

A business implements immutable backups in a separate account and validates restores of critical systems.

Safe Use of AI Assistants

An enterprise applies labels and DLP so confidential documents are not exposed through AI tools or shared externally.

Cyber Protection FAQ

Which protective controls should we implement first?

For most organizations, the highest-impact first steps are multi-factor authentication for all users, phishing-resistant methods for administrators, removal of unnecessary public exposure in cloud and network, EDR on all endpoints, timely patching of internet-facing systems, least privilege for administrative accounts and backups that are isolated from production. We confirm priorities with a short baseline assessment of your environment before recommending a roadmap.

What does zero trust mean in practice?

Zero trust means no user, device or network location is trusted by default. Every access request is evaluated based on identity, device health, location and risk, and users receive only the access they need. In practice, this involves strong authentication, conditional access policies, device management, segmentation of applications and data, and continuous monitoring. It is a journey implemented in stages, not a single product purchase.

Will new security controls disrupt our employees?

Poorly planned controls can, which is why we pilot changes with representative groups, tune policies based on feedback and communicate clearly before each rollout. Modern options such as passkeys, single sign-on and risk-based conditional access often improve the user experience while increasing security. We plan rollouts in waves and provide help desk guidance so issues are resolved quickly.

Can you work with our existing security vendors?

Yes. We are vendor-neutral and frequently work with Microsoft, Okta, CrowdStrike, Zscaler, Cloudflare, AWS, Google Cloud and others. Many organizations already own capable controls through existing licenses, such as Microsoft 365 E3 or E5, and do not use them fully. We start by maximizing what you have and only recommend new products when there is a clear, documented gap.

How do you protect against ransomware specifically?

Ransomware protection combines prevention, containment and recovery. We reduce initial access risk with MFA, patching and email security, limit lateral movement with least privilege and segmentation, detect precursor behavior with EDR, and ensure recovery with immutable, isolated backups and tested restore procedures. Response playbooks and exercises complete the picture, so your team knows exactly what to do if an attack begins.

How is cyber protection work delivered and priced?

Assessments and specific implementations, such as an identity hardening project or landing zone build, are delivered as fixed-scope projects priced by environment size and complexity. Ongoing posture management, policy tuning and reviews can be provided as a dedicated team or managed service. All engagements include weekly written updates and documentation, and we provide a clear estimate after an initial scoping conversation.
