You have identified the need for a cryptography expert to protect your company’s sensitive data, communications, and digital assets. Perhaps you are considering hiring an in-house resource, or engaging a freelancer or a temporary contractor.

The question we pose is simple: why hire or staff, when you can have a turnkey project designed by cybersecurity experts, already tested, certified, and ready to be implemented?

With ISGroup, cryptographic expertise transforms into a high-value service, not a personnel cost to manage.

Skills and technologies

What a cryptography expert does

A cryptography professional, integrated into an ISGroup project, handles:

• Designing and implementing secure cryptographic algorithms, whether standard or custom (AES, RSA, ECC, SHA-2).
• Analyzing vulnerabilities in existing encryption systems.
• Evaluating the cryptographic robustness of applications, databases, communications, and IoT devices.
• Integrating cryptography into business processes, complying with standards and regulations.
• Building systems for secure cryptographic key management (KMS, HSM).
• Implementing end-to-end encryption for APIs, files, data in transit, and at rest.
• Strengthening cryptographic protocols (TLS, IPsec, SSH).

Certifications and recognitions

ISGroup professionals hold internationally recognized certifications:

• Certified Encryption Specialist (EC-Council)
• GIAC Cryptography (GCPN)
• Certified Information Systems Security Professional (CISSP)
• ISO/IEC 27001 Lead Implementer
• Direct experience in regulated environments (PCI-DSS, GDPR, DORA, NIS2)

Technologies used

In our projects, we integrate cryptographic technologies and advanced tools:

• OpenSSL, BouncyCastle, Libsodium

When you need a cryptography expert

Typical use cases

A cryptography expert becomes essential in contexts such as:

• Protection of intellectual property or highly sensitive data (healthcare, finance, defense, Industry 4.0).
• Securing internal and external communications.
• SaaS or mobile applications that must protect end-user data.
• Regulatory compliance with GDPR, NIS2, PCI-DSS, ISO 27001, which requires the encryption of personal and sensitive data.
• Updating legacy systems with obsolete protocols or weak encryption.

Turnkey project vs. direct hiring

Hiring an in-house cryptography expert or working on a time-and-material basis involves several limitations:

Hiring / Time & Material	ISGroup Project
Continuous and unpredictable costs	Fixed budget, turnkey
Difficulty finding vertical skills	Access to specialized teams
Risk of dependency on a single resource	Documented and transferable method
Long onboarding times	Immediate and scalable delivery
No guarantee of results	Guaranteed SLAs and KPIs

With an ISGroup project, cryptographic expertise is integrated into a complete service, with the guarantee of measurable results and ensured regulatory compliance.

How our approach works

Initial analysis

We analyze:

• The technological and regulatory context in which you operate.
• The data to be protected and the attack surfaces.
• The critical issues of existing systems and future requirements.
• Integration, performance, and scalability needs.

Everything is translated into a detailed analysis document, upon which we build the intervention plan.

Custom implementation

Based on the context, we design and implement:

• Secure and high-performance cryptographic algorithms, standard or custom.
• Scalable key management systems.
• Encryption of data in transit and at rest, integrated into your applications or services.
• Integration into business processes and complete technical documentation.
• Compliance support and preparation for security audits.

Measurable results

Every ISGroup project includes:

• Performance benchmarks of the cryptographic solutions.
• Robustness and attack resistance tests.
• Complete, signed, and transferable documentation.
• Training for your internal team, for autonomous management.

Frequently asked questions

• Why should I outsource a cryptography project?
• Cryptography is a highly specialized technical field. Hiring an in-house expert is complex and expensive. Relying on ISGroup means having immediate results, an expert team, a consolidated methodology, and guaranteed regulatory compliance.
• Can our developers integrate the work of the cryptography expert?
• Absolutely. Our project is built to cooperate with your development team and provide everything necessary for proper integration: documentation, APIs, best practices, and post-delivery support.
• How long does a cryptography project last?
• From 20 to 60 working days, depending on complexity. Each project is quoted after the initial analysis and includes clearly defined timelines, costs, and expected results.
• How do you ensure code security?
• We use private repositories, encrypted communication channels, and secure versioning. We can also operate on-premise or in isolated environments, upon request.
• Do you also offer cryptographic audits on existing solutions?
• Yes. We can review legacy systems or custom developments already in use, providing a cryptographic vulnerability report with operational guidance.
