Our Services
Cybersecurity Services
Most breaches are not sophisticated. They happen because a dependency was three years out of date, because an administrative interface was reachable from the public internet, because a departed employee's account was never disabled, or because someone reused a password that had already appeared in a public breach. The attacks that make headlines are rare; the attacks that actually affect businesses are mundane and largely preventable.
Atisolve provides practical security work for applications and infrastructure: finding what is exposed, fixing what matters most, and putting in place the monitoring that shortens the time between something going wrong and someone noticing. We work with businesses that need to satisfy a customer's security review, businesses that have had an incident, and businesses that simply want to know where they stand.
Where Real Risk Concentrates
Security spending is often misallocated toward visible measures while the actual exposure sits elsewhere. In our experience the following account for a disproportionate share of genuine risk in small and mid-sized organisations.
Outdated Dependencies
Applications built on frameworks and libraries with published, exploitable vulnerabilities. Attackers scan for these automatically; no targeting is involved.
Exposed Interfaces
Admin panels, database ports, staging environments and management consoles reachable from the internet, frequently with default or weak credentials.
Credential Reuse
Staff using passwords that already appear in public breach datasets, on accounts without multi-factor authentication.
Excessive Access
Users and service accounts holding far more permission than their role requires, turning a single compromised account into full access.
Unencrypted or Over-Retained Data
Sensitive data stored in plain text, or kept long after any business need, expanding the impact of any breach that does occur.
No Detection
Absent or unmonitored logging, so an intrusion continues undetected for months rather than being caught in hours.
What We Do
Assessment
We establish what you actually have exposed: which services are internet-facing, what software and versions are running, where sensitive data lives, who has access to what, and which third parties hold your data. Most organisations discover things they had forgotten during this stage — a staging server still running, an old subdomain pointing at a decommissioned service, an integration nobody uses.
Application Security Review
We review application code and behaviour against the categories that actually cause breaches: injection flaws, broken authentication and session handling, missing authorisation checks on server endpoints, insecure direct object references, unsafe deserialisation and exposure of sensitive data in responses or logs.
Infrastructure Hardening
We reduce what is reachable and tighten what remains: network segmentation, firewall rules that default to denial, removal of unnecessary services, enforced encryption in transit and at rest, and secrets moved out of code and configuration files into a managed secret store.
Access Control Review
We audit accounts and permissions, remove access that is no longer needed, enforce multi-factor authentication on anything privileged, and separate administrative accounts from everyday ones. Dormant accounts belonging to former staff and contractors are a recurring finding.
Monitoring and Detection
We configure logging that captures what matters — authentication events, permission changes, administrative actions, unusual data access — and alerting that reaches a person. Logs nobody reads provide forensic value after an incident but prevent nothing during one.
Response Planning
We help define what happens when something goes wrong: who is contacted, how systems are isolated, how evidence is preserved, and what the notification obligations are. Incidents are handled far better when the plan was written before the pressure arrived.
Application Security in Detail
Authentication and Session Handling
Authentication is where the most damaging flaws appear because compromise grants everything downstream. We look at password storage — hashing with a modern algorithm, never encryption or plain text — session token generation and expiry, secure and httpOnly cookie flags, protection against fixation and replay, and whether multi-factor authentication is available and enforced for privileged accounts. Password reset flows deserve particular scrutiny, as they are a common bypass route: predictable tokens, tokens that do not expire, and responses that disclose whether an account exists are all frequent findings.
Authorisation
Authentication establishes who someone is; authorisation determines what they may do. The most common serious flaw we find is an endpoint that checks the former but not the latter — a user can retrieve another user's record simply by changing an identifier in the request. The interface may hide the option, but the API does not enforce it. Every server endpoint must verify that the authenticated user is permitted to act on the specific resource requested, and that check must live on the server, since anything client-side can be bypassed trivially.
Input Handling and Injection
Injection vulnerabilities arise when input is treated as instruction. Parameterised queries eliminate SQL injection; output encoding appropriate to context prevents cross-site scripting; careful handling of user-supplied paths prevents traversal. We also examine file upload handling, where the risks include content type spoofing, executable uploads and files written to locations the web server will serve directly.
Dependency and Supply Chain Risk
Modern applications are largely assembled from third-party packages, and each one is a potential entry point. We audit dependency trees for known vulnerabilities, identify packages that are unmaintained or have changed ownership suspiciously, and set up automated scanning so new advisories surface as they are published rather than at the next annual review. Keeping dependencies current is unglamorous and is among the highest-value security activities available.
Data Protection
Reducing the impact of a breach is as valuable as reducing its likelihood, and considerably more achievable. The starting point is knowing what you hold, where it is, and why. Organisations routinely discover during this exercise that they retain personal data with no current business purpose, copied into analytics systems, log files, backups and developer environments where it was never intended to live.
From there the work is practical: encrypt sensitive data at rest and in transit, minimise what is collected in the first place, delete what is no longer needed on a defined schedule, mask or synthesise data used in non-production environments, and restrict access so that a compromised account exposes a subset rather than everything. Backups need the same protection as live data, and need testing — an untested backup is a hope rather than a control, and ransomware specifically targets backups.
Cloud and Infrastructure Exposure
Cloud platforms are secure by default in some respects and dangerously permissive in others, and the difference is not always obvious. Storage buckets made public during a debugging session and never reverted, security groups opened to the whole internet rather than a specific range, and access keys committed to a repository are among the most common causes of data exposure. None of them require any skill to exploit once discovered, and automated scanners find them within hours of their appearing.
We review cloud configuration against the exposure it creates: what is publicly reachable and whether it needs to be, whether identity and access policies grant the minimum necessary permission or the convenient maximum, whether encryption is enabled on storage and databases, and whether audit logging is switched on and retained. We also look at how infrastructure changes are made — configuration applied by hand drifts and cannot be reviewed, whereas infrastructure defined as code can be inspected, versioned and rolled back.
Service accounts and machine credentials deserve specific attention because they are frequently long-lived, widely shared and rarely rotated. An access key created during an initial setup, embedded in a script and forgotten, will typically still work years later and often carries far broader permission than the task requires. Inventorying these, scoping them down and putting rotation in place removes a category of risk that no amount of attention to user passwords addresses.
Compliance and Customer Security Reviews
Many businesses first take security seriously because a customer demands it. Enterprise procurement now routinely includes security questionnaires and evidence requirements, and failing them costs contracts. Regulatory obligations — data protection law, sector-specific rules for healthcare and financial services, payment card requirements — add their own demands.
We help with both the substance and the documentation: implementing controls that genuinely reduce risk, and producing the evidence that demonstrates them. We are direct about the distinction, because compliance and security are related but not identical. It is entirely possible to pass an audit while remaining exposed, and equally possible to be well defended but unable to prove it. Both gaps are worth closing, for different reasons.
Security in the Development Process
Security added at the end is expensive and incomplete. Built into development, it is largely routine. We help teams adopt practices that catch problems early: dependency scanning and secret detection in the build pipeline, code review that includes security considerations, threat modelling for features that handle sensitive data or money, and separate environments so that testing never touches production data.
The cultural element matters more than the tooling. Developers who understand why a control exists write more secure code by default than developers handed a checklist. We work alongside teams rather than delivering findings from a distance, because the objective is that the next system is built well, not merely that this one is patched.
Getting Started
An assessment is the sensible entry point. It is bounded, produces a concrete prioritised list, and tells you where your actual exposure is rather than where you assume it is. If you are responding to a customer security review or dealing with an incident, tell us that context — the immediate priorities differ considerably between proving a control exists and containing an active compromise. We will be straightforward about what we find, including when the answer is that your exposure is lower than you feared and the sensible course is a small number of targeted fixes rather than a programme of work. Get in touch to discuss where you currently stand.
Frequently Asked Questions
We are small. Are we really a target?
Most attacks are opportunistic rather than targeted. Automated tools scan the entire internet for known vulnerabilities and exposed services, and they do not check company size first. Smaller organisations are often easier to compromise precisely because they assume they are not worth attacking, which is exactly what makes them worth attacking.
Where should we start if we have done nothing so far?
An assessment, because you cannot prioritise what you have not measured. In practice the highest-value early actions are consistent: enforce multi-factor authentication on email and administrative accounts, get dependencies up to date, remove internet exposure from anything that does not need it, and verify that backups exist and restore successfully. Those four cover a large share of realistic risk.
How often should security be reviewed?
Continuously for dependencies, since new vulnerabilities are published constantly and automated scanning handles this cheaply. More substantial reviews annually, and specifically whenever something significant changes — a major feature involving sensitive data, a new integration, a cloud migration or a change in who has access.
What should we do if we think we have been breached?
Preserve evidence before changing anything, because rebuilding a compromised server destroys the information needed to establish scope. Isolate affected systems rather than powering them off. Then establish what was accessed, over what period, and what your notification obligations are. We assist with incident response, and the businesses that handle incidents best are those that decided these steps in advance.
Does penetration testing cover everything?
No. A penetration test is a point-in-time assessment of what an attacker could achieve against a defined scope. It is valuable, but it does not cover what happens after new code ships next month, and it does not address process weaknesses such as access management or incident response. It is one input rather than a complete programme.
Can you work with our existing development team?
Yes, and that is usually the most effective arrangement. We review, advise and work alongside your developers so that the knowledge stays with the team. Delivering a findings report to a team that then has to interpret it alone tends to produce partial fixes and repeat findings the following year.
Do we need a full-time security person?
Most small and mid-sized organisations do not, and hiring one before the basics are in place is poor sequencing. What matters more is that someone owns security as a defined responsibility, that automated scanning runs continuously, and that there is a route to expertise when something needs judgement. A dedicated hire becomes justified as headcount and regulatory exposure grow.
How do we secure staff accounts without making work impossible?
Multi-factor authentication on email and administrative systems, a password manager so people are not reusing credentials, and access reviewed when roles change. These are modest impositions with disproportionate benefit. Policies that force frequent password changes or block legitimate tools tend to be circumvented, which leaves you less secure than before.
What about employees using personal devices?
It is common and manageable, but it needs deciding rather than tolerating by default. The practical questions are what company data may be accessed from personal devices, whether that data can be remotely removed if a device is lost or someone leaves, and whether devices must meet minimum requirements such as encryption and screen locks.
Are cloud providers responsible for our security?
Partly, and the boundary is where most confusion arises. The provider secures the underlying infrastructure; you remain responsible for configuration, access control, your application code and your data. Storage left publicly readable is your responsibility, not theirs. Understanding exactly where that line falls for the services you use is worth doing explicitly.
