É necessário acesso interno à empresa-alvo?

Não. A avaliação é conduzida a partir da superfície de ataque externa da empresa-alvo, observável pela internet. Isso permite examinar o risco cibernético antes do fechamento, mesmo quando o acesso à infraestrutura interna ainda não foi concedido.

A avaliação interfere na operação da empresa-alvo?

A avaliação é conduzida de forma externa e não exige a participação da empresa-alvo. Ela observa a exposição acessível pela internet, da mesma perspectiva de um agente externo, sem instalar componentes na infraestrutura avaliada.

O resultado serve para a negociação do negócio?

Sim. A avaliação traduz a exposição cibernética em uma leitura de risco apropriada para o comitê de investimento. Quando há exposições materiais, elas se tornam um elemento concreto a ser considerado na operação, e não uma surpresa posterior ao fechamento.

A avaliação pode continuar após o fechamento?

Sim. A visão da superfície de ataque externa produzida na due diligence serve de base para o acompanhamento contínuo da empresa adquirida e para o plano de integração de segurança, dando continuidade ao trabalho iniciado antes da operação.

DUE DILIGENCE CYBER · M&A

Understand the cyber risk before closing the deal.

In a merger or acquisition, the acquired company brings with it its entire cybersecurity posture—including exposures that are not documented in any transaction documents. CSURFACE evaluates the external exposure of a target company independently, providing to the due diligence process a technical perspective that questionnaires and declarations cannot achieve.

THE CHALLENGE

Cyber risk is an inherited asset

An acquisition transfers to the buyer the assets, contracts, and security posture of the target company. Unaddressed vulnerabilities, inadequate configurations, legacy infrastructure from previous operations, and exposed credentials integrate into the perimeter of the acquiring organization. When these conditions only come to light after closing, they cease to be a negotiation variable and become a cost.

Traditional cyber due diligence faces a practical limitation: access to the target company's internal infrastructure is rarely granted before closing, and available information tends to be self-declared. The result is a superficial assessment of a risk that may be material. A way is needed to examine the exposure of the target company from the outside without relying on its cooperation.

WHAT THE ASSESSMENT DELIVERS

A technical reading of the target company's exposure

The elements that CSURFACE brings to the cyber due diligence process.

External surface map

The platform discovers the assets that the target company exposes to the internet — including legacy infrastructure and services not included in formal inventories — and classifies them by relevance.

Prioritized exposures

The vulnerabilities and inadequate configurations identified are ordered by real exploitability, separating the critical from those with lesser impact.

Supplier digital chain

The assessment reveals the embedded third-party supply chain within the target company's assets, expanding understanding of dependencies that will be inherited in operations.

Compromise indicators

The platform identifies corporate credentials exposed and other signs suggesting that the target company may already have been a victim of compromise.

Risk in decision language

The assessment result is translated into a clear reading of risk, appropriate for informing the investment committee and operational decisions.

Foundation for integration

The vision produced in the assessment serves as a starting point for the post-closing security integration plan, with priorities already identified.

HOW IT WORKS

A cyber diligence that fits the business window

A cyber due diligence is conducted externally without interfering with the target company.

Scope definition

Starting from the target company's domain, CSURFACE defines the assessment and initiates the discovery of external attack surface without needing internal access.

Discovery and analysis

The external surface is mapped, exposures are identified and prioritized, and the digital supply chain of suppliers is brought into the assessment view.

Insight for decision

Findings are consolidated into a risk view appropriate for the due diligence process, ready to inform negotiation and operation.

FREQUENTLY ASKED QUESTIONS

FAQ

Is internal access to the target company required?

No. The assessment is conducted from the external attack surface of the target company, observable via the internet. This allows for an examination of cyber risk before closing, even when internal infrastructure access has not yet been granted.

Does the assessment interfere with the operation of the target company?

The assessment is conducted externally and does not require the participation of the target company. It observes the exposure accessible via the internet from an external perspective, without installing components on the evaluated infrastructure.

Does the result serve for business negotiations?

Yes. The assessment translates cyber exposure into a risk reading appropriate for the investment committee. When there are material exposures, they become a concrete element to be considered in operations, not a surprise after closing.

Can the assessment continue after closing?

Yes. The external attack surface view produced during due diligence serves as the basis for continuous monitoring of the acquired company and for the security integration plan, continuing the work initiated before the operation.
