Question 1

What is PCI DSS Level 1?

Accepted Answer

PCI DSS Level 1 is the highest tier of payment card industry security certification. It requires annual on-site assessments by a Qualified Security Assessor (QSA), quarterly network vulnerability scans, and penetration testing. Fewer than 1% of payment processors achieve and maintain Level 1 certification (PCI Security Standards Council).

Question 2

How does P2PE protect my business?

Accepted Answer

Point-to-Point Encryption (P2PE) encrypts card data at the moment of capture in the terminal hardware. The encrypted data passes through your network as unreadable ciphertext — even if intercepted, it cannot be decrypted. This removes your network from PCI scope and dramatically reduces your compliance burden.

Question 3

What is tokenization?

Accepted Answer

Tokenization replaces sensitive card numbers with randomly generated, non-reversible tokens. These tokens are meaningless if stolen — they cannot be used to make purchases or reverse-engineered to reveal the original card number. Tokens can only be mapped back to card data within PaySec's secure vault.

Question 4

How does PaySec detect fraud?

Accepted Answer

PaySec uses multi-layered fraud detection: machine learning models trained on billions of transactions (based on PaySec merchant data, Q1 2026), real-time velocity analysis, AVS/CVV verification, 3D Secure authentication, geolocation checks, and device fingerprinting. Suspicious transactions are flagged for review or automatically declined based on configurable risk thresholds.

Question 5

What happens in the event of a security incident?

Accepted Answer

PaySec's incident response team activates within minutes. The documented response plan includes containment, investigation, notification, and remediation procedures. Merchants receive timely communication and are covered by breach protection insurance included with every account.

Question 6

What is SOC 2 Type II and why does it matter?

Accepted Answer

SOC 2 Type II is an audit standard that evaluates a company's security controls over an extended period (typically 6-12 months). Unlike Type I which is a point-in-time snapshot, Type II verifies that security controls are consistently operational. PaySec's SOC 2 Type II report is available to merchants and their auditors upon request.

Question 7

How often is PaySec's security independently audited?

Accepted Answer

PaySec undergoes annual PCI DSS Level 1 assessments by a Qualified Security Assessor, annual SOC 2 Type II audits, quarterly external vulnerability scans by an Approved Scanning Vendor, and semi-annual penetration tests by independent security firms.

Question 8

Does PaySec's security reduce my own compliance requirements?

Accepted Answer

Yes. Using PaySec's P2PE-certified terminals reduces your PCI scope to the simplest SAQ level (P2PE, 33 questions) (PCI Security Standards Council). Using hosted checkout for eCommerce reduces scope to SAQ A (22 questions). Less scope means fewer security controls you need to maintain.

Question 9

How is my liability affected if PaySec has a breach?

Accepted Answer

PaySec includes up to $100,000 in breach protection coverage with every merchant account (based on PaySec merchant data, Q1 2026). This covers forensic investigation, customer notification, and card brand fines. PaySec has maintained a zero-breach record since inception.

Question 10

What encryption is used for data at rest?

Accepted Answer

Data at rest is encrypted with AES-256 encryption in FIPS 140-2 validated hardware security modules. Encryption keys are managed through a multi-party key ceremony process and rotated on a defined schedule. No single individual has access to complete key material.
