AI is helping attackers accelerate reconnaissance and identify exploitable weaknesses. As payment institutions add new services and integrations, their attack surfaces can also expand. Together, these pressures make it increasingly important to test security controls, rehearse incident response, and maintain continuous visibility into threats.
Consequently, traditional security measures alone are increasingly insufficient. Protecting payment systems requires coordinated controls across infrastructure, applications, payment authorization, and operations. Weaknesses within or between these layers can expose customer funds, compromise sensitive information, or disrupt critical services. Institutions supporting Web3 payments must also address risks associated with crypto-asset key management, transaction signing, and on-chain execution.
Against this backdrop, BlockSec is launching its Payment Security Solution, which brings together security assessments, penetration testing, red team assessments, and continuous monitoring and response. These services help institutions identify weaknesses, validate their defenses, prepare for incidents, and detect and respond to emerging threats across fiat currency to digital assets.
Three Core Priorities of Payment Security
Asset Security
Asset security protects customer funds and other assets held or transferred through a payment institution’s systems. In practical terms, it means safeguarding funds against risks such as unauthorized transfers, malicious changes to refund, withdrawal, or settlement account details, and duplicate charges.
In traditional payment scenarios, key risks include account takeover (ATO), payment authorization bypass, and settlement errors. Institutions supporting Web3 payments must additionally secure key management, transaction signing, and on-chain execution.
Ultimately, asset security means ensuring that every payment is properly authorized, the intended recipient receives the correct amount, and each transaction is accurately and consistently recorded in the ledger.
Data Security
Data security protects sensitive customer and operational information against unauthorized access, disclosure, alteration, and loss through controls governing access, use, storage, and retention.
In traditional payment scenarios, risks include the exposure of identity information, account data, and transaction records; employee access beyond what their roles require; and data leaks through staging or test environments. Institutions supporting Web3 payments must also protect the links between wallet addresses and real-world identities, along with signing requests, API keys, and node credentials.
Effective data protection requires institutions to enforce access, use, and retention controls consistently across systems and environments.
Business Security
Business security focuses on operational resilience: maintaining critical payment services during disruptions and restoring them safely afterward. Recovery must also account for payment integrity, including duplicate charges, missing transactions, and inconsistent ledger records.
In traditional payment scenarios, disruptions can arise from failures in cloud infrastructure, databases, networks, or payment channels. Institutions supporting Web3 payments must also prepare for blockchain congestion, block production halts, gas fee spikes, and failures in the blockchain infrastructure and third-party services they depend on, such as RPC endpoints, nodes, indexers, relayers, and, where applicable, sequencers, cross-chain bridges, and oracles.
Effective recovery requires institutions to reconcile transaction and ledger records and prevent recovery procedures from introducing further errors.
Our Services
BlockSec combines security assessment and penetration testing with incident response planning and ongoing monitoring. The approach covers prevention and preparedness before an incident, detection and containment during an incident, and investigation, recovery, and improvement afterward.
Each service addresses a different question: where are the weaknesses, how could they be exploited, how effectively would the team respond, and how can emerging threats be detected and addressed?
End-to-End Payment Security Assessment
BlockSec provides security audits and expert advisory services tailored to each payment institution’s business, covering the entire flow of incoming and outgoing funds. We assess the soundness of fund flow logic and identify weaknesses that attackers could exploit along the way.
By reviewing the systems, controls, and trust boundaries supporting these processes, we help payment institutions identify weaknesses that could lead to unauthorized transfers, incorrect account credits, or settlement discrepancies. Furthermore, we provide consultation and practical remediation guidance, helping institutions prioritize improvements and strengthen security throughout the payment lifecycle.
Security Audits and Penetration Testing
BlockSec’s blockchain penetration testing combines application, network, and cloud security expertise with a deep understanding of how crypto funds are authorized and moved.
Based on the findings of the security assessment, we conduct targeted penetration testing across APIs, signing interfaces, approval workflows, withdrawal controls, and the business logic governing fund movements. Testing focuses on whether identified weaknesses can be exploited individually or combined into a reproducible path to unauthorized fund movement.
Findings are documented with reproducible evidence, severity assessments, and remediation guidance, with retesting of agreed fixes to help institutions address confirmed risks.
Red Team Assessment
BlockSec designs tailored red team assessments and incident response exercises to evaluate payment institutions’ overall ability to respond to attacks.
Scenarios include credential compromise, manipulated signing requests, and unauthorized withdrawals. Red team assessments test whether security controls can block attacks or detect them promptly, while incident response exercises assess the team’s ability to triage alerts, escalate incidents, contain threats, and coordinate service recovery in an orderly manner.
Together, these exercises reveal weaknesses in security controls and gaps between documented response plans and how teams execute them under pressure.
Continuous Monitoring and Response
As payment systems and threats continue to evolve, security requires an ongoing commitment that extends beyond a single assessment.
To support ongoing protection, BlockSec extends its services beyond periodic assessments through Phalcon Security. The platform continuously monitors on-chain transactions as well as operational, interaction, financial, and multisig wallet risks. Where supported and configured with the necessary permissions, it can also trigger automated response actions to help block detected attacks before execution or limit further losses after detection.
