Fatih Yaşar offers end-to-end cyber security services, from technical auditing to incident response, to increase the security maturity of institutions. Each service heading is prioritized according to the current risk level and supported by a feasible improvement plan.

My Cyber Security Solutions

Cyber ​​security services are not just about technical interventions that come into play at the time of an attack; institution business continuity, data integrity, brand reputation and operational efficiency It is a holistic management model that simultaneously protects. The service approach offered by Fatih Yaşar first reveals the real state of the existing infrastructure, then measures the impact of threats and creates a feasible road map to reduce risks in order of priority. In this model, the aim is to systematically eliminate recurring vulnerabilities by going beyond the short-term problem-closing reflex. While network, application, data and access control are handled together at the technical layer; At the process layer, the monitoring, intervention, reporting and continuous improvement cycle operates uninterruptedly.

The service portfolio is designed to support this holistic framework. Ransomware Recovery In this service, the spread of the attack is stopped, affected systems are isolated and a safe return plan is created. During the decryption process, appropriate variant analysis is performed and data access is regained in technically possible scenarios. Data Recovery The service implements controlled recovery steps using forensic methods for lost or inaccessible files. Cloud Security helps reduce misconfiguration and authorization risks; Network Security with segmentation and rule hardening attack surface focuses on narrowing down. Application Security and Data Security strengthen protection at the code, API, and sensitive information layers. Firewall Security, System Reinstallation and Strategic Consultancy services complete the final link that makes the operation permanently secure.

The work flow is standard in all services but is flexible according to the priorities of the institution: preliminary evaluation, technical discovery, risk analysis, APPLICATION, verification test and reporting. Thanks to this approach, it becomes transparently visible which gap is critical and why, which step improves what, and how the next actions will be planned. Speed ​​is a priority in incidents requiring intervention; However, speed is not used in a way that undermines the integrity of evidence or system consistency. Planned progress, especially ransomware and reduces both financial loss and operational disruption in the event of a data breach. The findings are not just left as a technical list; It is presented with measurable metrics that will make it easier for business units to make decisions.

As a result, the cyber security services offered aim to ensure that institutions not only meet today's threats but also achieve security maturity ready for tomorrow's attack scenarios. Regular control mechanisms, up-to-date threat intelligenceWhen combined with access policy review and secure configuration standards, the infrastructure becomes more resilient. This durability not only includes technical security, but also traceability in audit processes, increased customer confidence and operational sustainability means. Fatih Yaşar's service model is based on a reactive intervention level, regardless of the size of the institution. proactive protection accelerates the transition to the level; Thus, risks can be managed, systems can be audited and growth plans can be maintained on safe ground.

In addition, the service model constantly involves not only technical teams but also the management layer. Thanks to regular status meetings, short risk summary reports and action tracking charts security investments measurable KPI linked to values. This approach positions security as a performance layer that protects business value, rather than a cost center. Thus, within the institution security awareness increases, decision-making speed increases and the level of preparedness for critical events is permanently strengthened.

Fatih Yaşar and Service Approach

Fatih Yaşar treats cyber security services not only as a technical task list, but as a resilience program compatible with the business goals of the institution. In this approach, each service; It is customized taking into account existing infrastructure, human resources, operational intensity and sector requirements. The priority is to establish a clear control model that protects the organization's most critical assets. Therefore, in the first step of the service process, the environment is analyzed, the risk level is measured and actions that will provide quick gains are determined.

During the implementation phase, technical depth and operational reality are managed together. This means that recommended security controls are not limited to theoretical accuracy only; It is deployed in a live system in a way that is sustainable, auditable and applicable by teams. In Fatih Yaşar's working model, reporting is not an important closing step, but a strategic tool that increases the quality of decision-making. In this way, institutions can concretely see not only which gap has been closed, but also which risk has been reduced and to what extent.

In the long term, the goal is to create a maturing security culture rather than one-off interventions. Service continuity is maintained through regular verification tests, rule updates, and post-incident remediation plans. As a result, the institution emerges from a structure that responds reactively to threats; It moves to a security architecture that is proactive, measurable and supports growth. This transformation lies at the core of the service value offered by Fatih Yaşar: fewer interruptions, higher trust and stronger digital continuity.

For this reason, communication discipline is at the forefront as much as technical delivery in the services carried out with Fatih Yaşar. Clear status updates are shared throughout the process, implementation priorities are determined together, and the business impact of each step is clearly reported. With this model, institutions achieve a sustainable corporate structure that is more resistant and auditable not only against external threats but also against internal process errors.

01 What is Ransomware Recovery?
expand_more
Ransomware Recovery is the process of determining the scope of the incident, isolating the spread, and creating a secure fallback plan without completely stopping the operation of encrypted systems. In this service, not only file access, but also lateral movements in the network, affected user privileges and backup integrity are analyzed together. Technically, the aim is to reveal the root cause of the attack, reduce the risk of recurrence, and restart the organization's business continuity in a controlled manner, while preserving the integrity of the evidence.
02 What is Decryption?
expand_more
Decryption is the attempt to make data accessible again by taking advantage of existing keys, vulnerabilities or known algorithm behaviors in certain ransomware variants. The first step in this process is to verify the malware family classification and the encryption method used. Then, data consistency is tested by testing secure copies. Enterprise-grade decrypt service reduces the risk of permanent data loss due to incorrect intervention and makes the recovery process manageable with technical evidence.
03 What is Data Recovery?
expand_more
Data Recovery is the process of retrieving deleted, corrupted or inaccessible digital data using forensic and technical methods. The probability of recovery is calculated by examining the disk structure, file system integrity, partition table and log records together. In corporate environments, this service is applied not only to restore files, but also to determine the cause of data loss and plan technical measures to prevent its recurrence. Thus, operational downtime is reduced and critical information assets are protected.
04 What is Cloud Security?
expand_more
Cloud Security is a continuous protection model that includes identity management, access control, data encryption, log monitoring and misconfiguration controls in IaaS, PaaS and SaaS environments.

An effective firewall service is not just about adding rules; Rule cleaning, closing unnecessary permissions, log correlation and performance optimization are carried out together. In this way, the security level increases and network delay is kept under control. Regular firewall monitoring in corporate environments is one of the most critical sustainable security steps that reduce the attack surface.
09 What is System Reinstallation?
expand_more
System Reinstallation is the process of reactivating the infrastructure with a clean, secure and verified structure after an attack or critical disruption. This service goes beyond the formatting approach; Secure image usage, hardening policies, up-to-date patch management and redesign of access rights are implemented. Then, workloads are moved in a controlled manner and function tests are performed. From a corporate perspective, the goal is not just to run the system, but to create a permanent basis that will prevent the same vulnerability from occurring again.
10 What is Strategic Consulting?
expand_more
Strategic Consultancy is a service of planning resource, process and technology investments in the right order by aligning the security goals of the organization with its business goals. In this context, the threat model, budget priorities, control requirements and operational capacity are evaluated together. Technical suggestions are transformed into road maps that decision makers can implement.
