Our Security Services

Comprehensive security solutions to protect your digital assets

Web Security Assessment

We dive deep into your web applications, thinking like sophisticated attackers to uncover hidden risks that automated tools overlook.

Key Vulnerabilities We Target

  • Common issues like injection attacks, cross-site scripting, and broken access controls from OWASP guidelines.
  • Advanced threats such as race conditions, server-side request forgery, and prototype pollution that require manual exploration.
  • Business logic flaws, like manipulating workflows to bypass payment checks or abusing promo codes for unlimited discounts.
  • Real-world abuse cases, including account takeovers through weak password resets or session fixation.
  • Role-based access problems where users escalate privileges to view sensitive data.
  • Authentication weaknesses, authorization gaps, poor session management, and trust boundary violations across components.

Business Impact We Prevent

  • Financial losses from fraudulent transactions or unauthorized fund transfers.
  • Data abuse leading to customer identity theft and legal liabilities.
  • Compliance risks resulting in hefty fines under regulations like GDPR.
  • Reputation damage from public breaches that erode client trust.

Our manual testing expertise simulates complex attack chains, ensuring startups and growing companies stay ahead of threats with practical, actionable insights.

Mobile App Security Assessment

We scrutinize your mobile apps with an attacker's perspective, revealing subtle flaws in device interactions that scanners can't detect.

Key Vulnerabilities We Target

  • Standard risks including insecure data storage, improper platform usage, and insufficient cryptography per OWASP Mobile Top 10.
  • Out-of-the-box issues like jailbreak detection bypasses, runtime hooking, and side-channel leaks from app behaviors.
  • Business logic vulnerabilities, such as tampering with local data to fake transactions or exploit in-app purchases.
  • Real-world scenarios like intercepting sensitive communications or abusing deep links for unauthorized access.
  • Role-based access flaws allowing standard users to unlock premium features.
  • Authentication bypasses, authorization inconsistencies, session persistence issues, and trust boundaries in app-to-server exchanges.

Business Impact We Prevent

  • Financial setbacks from app-based fraud or revenue leaks.
  • Data misuse exposing user personal information to competitors or criminals.
  • Compliance violations risking app removal from stores or regulatory penalties.
  • Reputation hits from user complaints about privacy invasions.

Through hands-on reverse engineering and exploitation simulations, we empower emerging businesses to build secure, trustworthy mobile experiences.

API Security Assessment

We probe your APIs as interconnected gateways, identifying chained exploits that automated checks miss in dynamic environments.

Key Vulnerabilities We Target

  • Core concerns like broken object level authorization, excessive data exposure, and injection flaws aligned with OWASP API Security Top 10.
  • Advanced vulnerabilities including mass assignment exploits, GraphQL depth attacks, and webhook manipulations.
  • Business logic errors, such as rate limit bypasses enabling denial-of-service or data scraping.
  • Real-world abuses like chaining API calls to extract confidential records or forge requests.
  • Role-based access issues where APIs leak admin endpoints to regular users.
  • Authentication token weaknesses, authorization scope creeps, session replay risks, and trust boundary crossings in microservices.

Business Impact We Prevent

  • Financial damage from API-driven fraud or unauthorized resource consumption.
  • Data exploitation compromising partner integrations and intellectual property.
  • Compliance failures leading to audits and sanctions.
  • Reputation erosion from service disruptions affecting customer loyalty.

Our attacker-minded manual assessments trace complex paths, helping scaling companies maintain robust, reliable API ecosystems.

Thick Client Security Assessment

We dissect your desktop applications layer by layer, uncovering client-side manipulations that evade standard scans.

Key Vulnerabilities We Target

  • Fundamental risks such as insecure communications, weak encryption, and improper input validation based on OWASP principles.
  • Sophisticated threats like memory dumping, DLL injection, and protocol reverse engineering.
  • Business logic bypasses, including altering client code to approve invalid operations or extract embedded secrets.
  • Real-world exploitations such as tampering with license checks or forging server responses.
  • Role-based access vulnerabilities enabling local privilege escalations.
  • Authentication flaws in stored credentials, authorization mismatches, session hijacking via local storage, and trust boundaries in client-server dialogues.

Business Impact We Prevent

  • Financial losses through pirated software or manipulated transactions.
  • Data theft allowing competitors to reverse-engineer proprietary features.
  • Compliance issues from exposed sensitive local data.
  • Reputation harm from user-discovered exploits spreading online.

With deep manual decompilation and scenario testing, we deliver practical defenses for startups relying on thick clients.

Infrastructure/Network Security Assessment

We map and assault your networks like persistent intruders, exposing lateral movement paths overlooked by automated tools.

Key Vulnerabilities We Target

  • Essential weaknesses including misconfigurations, weak protocols, and unpatched systems per OWASP and network best practices.
  • Advanced exploits like zero-day device vulnerabilities, VLAN hopping, and ARP poisoning variations.
  • Business logic flaws in network flows, such as bypassing firewalls through trusted zones.
  • Real-world attacks chaining weak endpoints to pivot into core systems.
  • Role-based access problems in segmented networks allowing cross-zone intrusions.
  • Authentication gaps in VPNs, authorization issues in NAC, session management in remote access, and trust boundary flaws between internal segments.

Business Impact We Prevent

  • Financial disruptions from ransomware locking critical operations.
  • Data breaches enabling industrial espionage or customer data sales.
  • Compliance penalties for failing standards like PCI DSS.
  • Reputation loss from downtime affecting service delivery.

Our real-world penetration simulations build resilient networks, fostering trust for growing enterprises.

Cloud Security Assessment

We navigate your cloud setups with an insider threat lens, revealing configuration chains that scanners fail to connect.

Key Vulnerabilities We Target

  • Primary risks like improper access controls, security misconfigurations, and account hijacking from OWASP Cloud Top 10.
  • Nuanced issues including over-permissive IAM roles, metadata service exploits, and container escape techniques.
  • Business logic vulnerabilities in cloud workflows, such as abusing auto-scaling for resource exhaustion.
  • Real-world abuses like cryptojacking through exposed buckets or lateral movement via shared services.
  • Role-based access flaws granting excessive permissions across tenants.
  • Authentication weaknesses in MFA setups, authorization drifts, session token exposures, and trust boundary issues in hybrid environments.

Business Impact We Prevent

  • Financial overages from unauthorized resource usage or data transfer costs.
  • Data leaks exposing trade secrets to public view.
  • Compliance risks triggering investigations and fines.
  • Reputation damage from cloud incidents hitting headlines.

Through expert manual audits and exploit proofs, we secure cloud growth for innovative companies.
