  • Security Testing Service

    Testhouse Ltd

    No one on the Internet is immune from security threats. The consequences of a security breach are great:revenue impact, damage to credibility, legal liability, and loss of customer trust. Security testing helps to make data and information on digital networks secure by identifying potential vulnerabilities and flaws in security mechanisms of the network, while ensuring compliance with latest recommended security standards. Security testing assures managements that their systems are secure from attack, vulnerabilities and provides end users with reassurance their data is protected and secured at all times.- Security testing can be carried out in conjunction with or independent of other testing processes- Security testing looks at stopping active intrusion attempts from external sources than fixing only inherent application flaws
