Internet Security Measures


This website's URL is prefixed by the secure HTTPS protocol. When sent via this protocol, data is protected by encryption to keep it secure from interception. Data cannot be modified or corrupted during transfer, intentionally or otherwise, without being detected.


Security is probably one of the most significant concerns for both the client and ourselves during an online transaction. In reality an online transaction is probably more secure than a card transaction in a shop or conducted over the telephone or by fax, as the information transmitted online is highly encrypted using complicated logarithm combinations.

The WorldPay payment system uses a combination of both established and innovative techniques to ensure the security and integrity of all sensitive data. Furthermore, WorldPay's web servers are certified by Thawte, a public Certificate Authority, ensuring that both the client and us may have confidence that nobody can impersonate WorldPay to obtain confidential information.

Transaction Encryption

The transfer of the purchase details from the Siam International Accounting Management Ltd. website to WorldPay is encapsulated using WorldPay's own encrypted and digitally-signed protocol. This uses a combination of standard methods such as PGP, RSA and MD5 to ensure that the information passed is secure and tamper-proof.

Data Storage

Data storage on WorldPay systems, and the communication between WorldPay and the worldwide banking networks, is regularly audited by the banking authorities to ensure a secure transaction environment. WorldPay also ensure that they stay up-to-date with the latest versions of any third-party code they use, and continually review their own proprietary code.


We do not accept Bitcoin as payment for our services and we have no intention of doing so until we can use it to seamlessly pay staff salaries and office expenses as we can with banknotes or a credit card.

Certain highly confidential elements of our work are held on the deep web.

The internet has often been descibed as an iceberg. A small part of all the data available on the Internet can be described as the "surface web" - the tip of the iceberg, above the surface.

This is the part of the World Wide Web which is readily accessible by anyone and can be found by searching through conventional search engines. Below this surface is where the deep web exists .

The deep web is also called the invisible web, since data stored on it does not appear through conventional search engines. For example, password-protected webpages and personal email accounts are considered part of the deep web because they cannot be found through a Google search. The deep web holds approximately ninety-five percent of all data on the Internet.
