How PESI turns information security into a strategic advantage

How PESI turns information security into a strategic advantage 

In the modern corporate world, where online transactions have become the heart of business operations, digitalization is not just a trend, but a consolidated reality.  

According to a study by the National Confederation of Industry (CNI), 70% of Brazilian companies have already adopted digitalization, marking the transition to an irreversible digital age.  

However, this transformation brings with it significant information security challenges. Faced with this reality, it is clear that information security has gone beyond the stage of recommendation to become an imperative necessity. 

The importance of the PESI - Strategic Information Plan 

In this scenario, the Strategic Information Security Plan (PESI) emerges as a crucial tool for organizations to align their strategic objectives with information security management.  

PESI is a compilation of goals and actions designed to strengthen information security within companies, covering governance, people, processes, technologies and compliance with applicable regulations.  

This plan is fundamental not only for data protection, but also for adapting organizations to current regulations, such as the LGPD (General Data Protection Act), ISO/IEC 27001 (Information Security Management System) and ISO/IEC 27002 (Code of Practice for Information Security Management), playing a vital role in planning information security actions. 

How PESI works 

The preparation of the PESI follows a detailed process that should be carried out over a period of 3 to 5 years, and can be reviewed annually depending on the client's specific needs.  

This process is divided into five main phases: 

1. Planning 

Planning begins with a detailed strategic survey, focused on the client's needs and expectations, ensuring that the PESI is aligned with the company's objectives.  

2. Diagnosis and Risk Assessment 

At this stage, a SWOT analysis is carried out to understand the strengths, weaknesses, opportunities and threats related to information security within the organization.  

3. Strategy development 

Strategy development is a process that involves drawing up a detailed plan of goals and actions designed to address the identified risks and strengthen the organization's security posture.  

4. Review and delivery 

After the strategy is completed, the PESI goes through a rigorous review phase, in which the plan and executive presentation are carefully examined to ensure their alignment with the company's strategic objectives and their suitability for the needs identified.  

5. Support 

The support phase is essential for the successful implementation of PESI.  

It includes holding regular meetings with the client to monitor the progress of the plan's execution, allowing strategies to be adjusted as necessary and ensuring that the plan remains relevant and effective in the face of changes in the business environment or threat landscape.  

PESI's main benefits 

By embarking on the journey of strengthening information security with the implementation of a Strategic Information Security Plan (SISP), organizations open the door to a wide range of transformative benefits.  

Get to know the main ones: 

Critical Asset Protection 

By identifying and classifying data and resources as critical, the plan establishes customized security measures that prevent unauthorized access and potential compromise.  

This not only ensures the integrity and availability of assets, but also maintains the confidentiality of sensitive information, a fundamental pillar in preserving competitive advantage and corporate reputation. 

Risk and Vulnerability Reduction 

Through a detailed risk assessment, the plan prioritizes the correction of faults and the reinforcement of critical areas, reducing the attack surface and the likelihood of security incidents.  

With this proactive approach, it is possible to prevent operational disruptions and minimize potential financial and reputational damage, contributing to business continuity. 

Developing a Safety Culture 

By involving all levels of the organization in training and awareness-raising, the plan fosters a shared understanding of the importance of security, encouraging safe behavior and the adoption of data protection practices.  

This cultural transformation strengthens internal security and promotes organizational resilience in the face of external threats. 

Improved Operational Efficiency 

The plan establishes clear processes and guidelines for security management, which allow the team to respond more quickly and effectively to incidents and threats.  

Continuous improvement, driven by PESI, not only improves the organization's defence capacity, but also promotes more efficient use of the resources dedicated to information security. 

Saving financial resources 

By avoiding security incidents, companies save on the costs associated with data loss, operational interruptions, system recovery and potential fines for non-compliance.  

These savings allow resources to be allocated more effectively, contributing to financial sustainability and strategic investments in other areas of the organization. 


By incorporating compliance requirements such as GDPR, LGPD, among others, the plan ensures that information security practices are in line with applicable laws and standards.  

This compliance not only avoids sanctions, but also strengthens the trust of customers and partners, which is essential for the development of solid and lasting business relationships. 

PESI: a strategic necessity  

By meticulously structuring and executing PESI, organizations not only shield their critical assets from cyber threats, but also pave the way for sustainable and resilient growth in the global competitive landscape.  

Don't wait until you face a security incident to take action.
